The low profile of the LMV721-N/722 make them possible to use in PCMCIA type III cards. Signal Integrity Signals can pick up noise between the signal source and the amplifier. By using a physically smaller amplifier package, the LMV721-N/722 can be placed closer to the signal source, reducing noise pickup and increasing signal integrity. Simplified Board Layout These products help you to avoid using long pc traces in your pc board layout. This means that no additional components, such as capacitors and resistors, are needed to filter out the unwanted signals due to the interference between the long pc traces. Low Supply Current These devices will help you to maximize battery life. They are ideal for battery powered systems. Low Supply Voltage TI provides ensured performance at 2.2V and 5V. These specifications ensure operation throughout the battery lifetime. Rail-to-Rail Output Rail-to-rail output swing provides maximum possible dynamic range at the output. This is particularly important when operating on low supply voltages. Input Includes Ground Allows direct sensing near GND in single supply operation. Protection should be provided to prevent the input voltages from going negative more than −0.3V (at 25°C). An input clamp diode with a resistor to the IC input terminal can be used. CAPACITIVE LOAD TOLERANCE The LMV721-N/722 can directly drive 4700pF in unity-gain without oscillation. The unity-gain follower is the most sensitive configuration to capacitive loading. Direct capacitive loading reduces the phase margin of amplifiers. The combination of the amplifier's output impedance and the capacitive load induces phase lag. This results in either an underdamped pulse response or oscillation. To drive a heavier capacitive load, circuit in Figure 23 can be used. Figure 23. Indirectly Driving A capacitive Load Using Resistive Isolation In Figure 23, the isolation resistor RISO and the load capacitor CL form a pole to increase stability by adding more phase margin to the overall system. the desired performance depends on the value of RISO. The bigger the RISO resistor value, the more stable VOUT will be. Figure 24 is an output waveform of Figure 23 using 100kΩ for RISO and 2000µF for CL.

Pulse Response of the LMV721-N Circuit in Figure 23 The circuit in Figure 25 is an improvement to the one in Figure 23 because it provides DC accuracy as well as AC stability. If there were a load resistor in Figure 23, the output would be voltage divided by RISO and the load resistor. Instead, in Figure 25, RF provides the DC accuracy by using feed-forward techniques to connect VIN to RL. Caution is needed in choosing the value of RF due to the input bias current of the LMV721-N/722. CF and RISO serve to counteract the loss of phase margin by feeding the high frequency component of the output signal back to the amplifier's inverting input, thereby preserving phase margin in the overall feedback loop. Increased capacitive drive is possible by increasing the value of CF. This in turn will slow down the pulse response. Figure 25. Indirectly Driving A Capacitive Load with DC Accuracy INPUT BIAS CURRENT CANCELLATION The LMV721-N/722 family has a bipolar input stage. The typical input bias current of LMV721-N/722 is 260nA with 5V supply. Thus a 100kΩ input resistor will cause 26mV of error voltage. By balancing the resistor values at both inverting and non-inverting inputs, the error caused by the amplifier's input bias current will be reduced. The circuit in Figure 26 shows how to cancel the error caused by input bias current. Figure 26.

It is useful as a computational amplifier, in making a differential to single-ended conversion or in rejecting a common mode signal. Figure 27. Difference Application (1) (2) Instrumentation Circuits The input impendance of the previous difference amplifier is set by the resistor R1, R2, R3 and R4. To eliminate the problems of low input impendance, one way is to use a voltage follower ahead of each input as shown in the following two instrumentation amplifiers. Three-op-amp Instrumentation Amplifier The LMV721-N/722 can be used to build a three-op-amp instrumentation amplifier as shown in Figure 28 Figure 28. Three-op-amp Instrumentation Amplifier The first stage of this instrumentation amplifier is a differential-input, differential-output amplifier, with two voltage followers. These two voltage followers assure that the input impedance is over 100MΩ. The gain of this instrumentation amplifier is set by the ratio of R2/R1. R3 should equal R1 and R4 equal R2. Matching of R3 to R1 and R4 to R2 affects the CMRR. For good CMRR over temperature, low drift resistors should be used. Making R4 slightly smaller than R2 and adding a trim pot equal to twice the difference between R2 and R4 will allow the CMRR to be adjusted for optimum.

As in the two-op-amp circuit, this instrumentation amplifier requires precise resistor matching for good CMRR. R4 should equal to R1 and R3 should equal R2. Figure 29. Two-op-amp Instrumentation Amplifier (3) Single-Supply Inverting Amplifier There may be cases where the input signal going into the amplifier is negative. Because the amplifier is operating in single supply voltage, a voltage divider using R3 and R4 is implemented to bias the amplifier so the input signal is within the input common-common voltage range of the amplifier. The capacitor C1 is placed between the inverting input and resistor R1 to block the DC signal going into the AC signal source, VIN. The values of R1 and C1 affect the cutoff frequency, fc = ½π R1C1. As a result, the output signal is centered around mid-supply (if the voltage divider provides V+/2 at the noninverting input). The output can swing to both rails, maximizing the signal-to-noise ratio in a low voltage system. Figure 30. Single-Supply Inverting Amplifier (4) Active Filter Simple Low-Pass Active Filter The simple low-pass filter is shown in Figure 31. Its low-pass frequency gain (ω → o) is defined by −R3/R1. This allows low-frequency gains other than unity to be obtained. The filter has a −20dB/decade roll-off after its corner frequency fc. R2 should be chosen equal to the parallel combination of R1 and R3 to minimize error due to bias current. The frequency response of the filter is shown in Figure 32. 12 Submit Documentation Feedback Copyright © 1999–2013, Texas Instruments Incorporated Product Folder Links: LMV721-N LMV722-N LMV721-N, LMV722-N www.ti.com SNOS414I – AUGUST 1999 – REVISED AUGUST 2013 Figure 31.

Frequency Response of Simple Low-pass Active Filter in Figure 31 Note that the single-op-amp active filters are used in to the applications that require low quality factor, Q(≤ 10), low frequency (≤ 5KHz), and low gain (≤ 10), or a small value for the product of gain times Q(≤ 100). The op amp should have an open loop voltage gain at the highest frequency of interest at least 50 times larger than the gain of the filter at this frequency. In addition, the selected op amp should have a slew rate that meets the following requirement: Slew Rate ≥ 0.5 x (ωH VOPP) X 10 −6V/µsec where • • ωH is the highest frequency of interest VOPP is the output peak-to-peak voltage Figure 33.

Since the LMV721-N is a low noise and low power op amp, it makes it an ideal candidate as a battery powered microphone preamplifier. The LMV721-N is connected in an inverting configuration. Resistors, R1 = R2 = 4.7kΩ, sets the reference half way between VCC = 3V and ground. Thus, this configures the op amp for single supply use. The gain of the preamplifier, which is 50 (34dB), is set by resistors R3 = 10kΩ and R4 = 500kΩ. The gain bandwidth product for the LMV721-N is 10 MHz. This is sufficient for most audio application since the audio range is typically from 20 Hz to 20kHz. A resistor R5 = 5kΩ is used to bias the electret microphone. Capacitors C1 = C2 = 4.7µF placed at the input and output of the op amp to block out the DC voltage offset.
