The FAN4113 is designed to operate from +1.2V to 5.5V (±2.75V) supplies. The common mode voltage range extends below the negative rail and the output provides rail-to-rail performance. The FAN4113 is designed on a complementary bipolar process and provides 36MHz of bandwidth and 8V/µs of slew rate at a low supply voltage of 1.2V. The combination of low power, rail-to-rail performance, low voltage operation, and tiny package options make the FAN4113 well suited for use in personal electronics equipment such as cellular handsets, pagers, PDAs, and other battery powered applications.

The FAN4113 is fabricated on a complimentary bipolar process, features a rail-to-rail output, and is unity gain stable. The typical non-inverting circuit schematic is shown in Figure 1. Power Dissipation The maximum internal power dissipation allowed is directly related to the maximum junction temperature. If the maximum junction temperature exceeds 150°C, some performance degradation will occur. It the maximum junction temperature exceeds 175°C for an extended time, device failure may occur. Overdrive Recovery Overdrive of an amplifier occurs when the output and/or input ranges are exceeded. The recovery time varies based on whether the input or output is overdriven and by how much the ranges are exceeded. The FAN4113 will typically recover in less than 50ns from an overdrive condition. Figure 3 shows the FAN4113 in an overdriven condition. +Vs 6.8µF + In + Rg 0.01µF Out Output Voltage (0.5V/div) FAN4113 G = 5V Vs = 2.7V Output Rf Input Figure 1: Typical Non-inverting Configuration RR Applications and Beyond The FAN4113 can be used with input signals that exceed its common mode input voltage range. Simply attenuate the input signal and increase the gain of the FAN4113, see Figure 2. First, select A1 so the FAN4113 common voltage range is not exceeded. Second, select Rf and Rg to get the desired overall gain for signal Vin. Finally, pick VDC for the desired output offset. Time (200µs/div) Figure 3: Overdrive Recovery Driving Capacitive Loads The Frequency Response vs. CL plot, illustrates the response of the FAN4113. A small series resistance (Rs) at the output of the amplifier, illustrated in Figure 4, will improve stability and settling performance.

Fairchild has evaluation boards to use as a guide for high frequency layout and as aid in device testing and characterization. Follow the steps below as a basis for high frequency layout: • Include 6.8µF and 0.01µF ceramic capacitors • Place the 6.8µF capacitor within 0.75 inches of the power pin • Place the 0.01µF capacitor within 0.1 inches of the power pin • Remove the ground plane under and around the part, especially near the input and output pins to reduce parasitic capacitance • Minimize all trace lengths to reduce series inductances Refer to the evaluation board layouts shown in Figure 6 for more information.
