Unlike traditional metal-gate CMOS – operational amplifiers, these devices utilize Texas Instruments silicon-gate LinCMOS process, OFFSET N1 giving them stable input offset voltages without OFFSET N2 sacrificing the advantages of metal-gate CMOS. This series of parts is available in selected grades of input offset voltage and can be nulled with one external potentiometer. Because the input common-mode range extends to the negative rail and the power consumption is extremely low, this family is ideally suited for battery-powered or energy-conserving applications. A bias-select pin can be used to program one of three ac performance and power-dissipation levels to suit the application. The series features operation down to a 1.4-V supply and is stable at unity gain. These devices have internal electrostatic-discharge (ESD) protection circuits that prevent catastrophic failures at voltages up to 2000 V as tested under MIL-STD-883C, Method 3015.1. However, care should be exercised in handling these devices as exposure to ESD may result in a degradation of the device parametric performance. Because of the extremely high input impedance and low input bias and offset currents, applications for the TLC251C series include many areas that have previously been limited to BIFET and NFET product types. Any circuit using high-impedance elements and requiring small offset errors is a good candidate for cost-effective use of these devices. Many features associated with bipolar technology are available with LinCMOS operational amplifiers without the power penalties of traditional bipolar devices. Remote and inaccessible equipment applications are possible using the low-voltage and low-power capabilities of the TLC251C series. In addition, by driving the bias-select input with a logic signal from a microprocessor, these operational amplifiers can have software-controlled performance and power consumption. The TLC251C series is well suited to solve the difficult problems associated with single battery and solar cell-powered applications. The TLC251C series is characterized for operation from 0°C to 70°C.

Under certain conditions, this SCR may be triggered into a low-impedance state, resulting in excessive supply current. To avoid such conditions, no voltage greater than 0.3 V beyond the supply rails should be applied to any pin. In general, the operational amplifier supplies should be applied simultaneously with, or before, application of any input signals. 16 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 TLC251, TLC251A, TLC251B, TLC251Y LinCMOS PROGRAMMABLE LOW-POWER OPERATIONAL AMPLIFIERS SLOS001F – JULY 1983 – REVISED MARCH 2001 APPLICATION INFORMATION using BIAS SELECT The TLC251 has a terminal called BIAS SELECT that allows the selection of one of three IDD conditions (10, 150, and 1000 µA typical). This allows the user to trade-off power and ac performance. As shown in the typical supply current (IDD) versus supply voltage (VDD) curves (Figure 4), the IDD varies only slightly from 4 V to 16 V. Below 4 V, the IDD varies more significantly. Note that the IDD values in the medium- and low-bias modes at VDD = 1.4 V are typically 2 µA, and in the high mode are typically 12 µA. The following table shows the recommended BIAS SELECT connections at VDD = 10 V. BIAS MODE AC PERFORMANCE BIAS SELECT CONNECTION† TYPICAL IDD‡ Low Medium High Low Medium High VDD 0.8 V to 9.2 V Ground pin 10 µA 150 µA 1000 µA † Bias selection may also be controlled by external circuitry to conserve power, etc. For information regarding BIAS SELECT, see Figure 3 in the typical characteristics curves. ‡ For IDD characteristics at voltages other than 10 V, see Figure 4 in the typical characteristics curves. output stage considerations The amplifier’s output stage consists of a source-follower-connected pullup transistor and an open-drain pulldown transistor. The high-level output voltage (VOH) is virtually independent of the IDD selection and increases with higher values of VDD and reduced output loading. The low-level output voltage (VOL) decreases with reduced output current and higher input common-mode voltage. With no load, VOL is essentially equal to the potential of VDD – /GND. input offset nulling The TLC251C series offers external offset null control. Nulling may be achieved by adjusting a 25-kΩ potentiometer connected between the offset null terminals with the wiper connected to the device VDD – /GND pin as shown in Figure 2. The amount of nulling range varies with the bias selection. At an IDD setting of 1000 µA (high bias), the nulling range allows the maximum offset specified to be trimmed to zero. In low or medium bias or when the amplifier is used below 4 V, total nulling may not be possible for all units. supply configurations Even though the TLC251C series is characterized for single-supply operation, it can be used effectively in a split-supply configuration when the input common-mode voltage (VICR), output swing (VOL and VOH), and supply voltage limits are not exceeded. circuit layout precautions The user is cautioned that whenever extremely high circuit impedances are used, care must be exercised in layout, construction, board cleanliness, and supply filtering to avoid hum and noise pickup, as well as excessive dc leakages.
