The TLE202xM circuitry includes input-protection diodes to limit the voltage across the input transistors; however, no provision is made in the circuit to limit the current if these diodes are forward biased. This condition sometimes occurs when the device is operated in the voltage-follower configuration and driven with a fast, large-signal pulse. Use a feedback resistor to limit the current to a maximum of 1mA to prevent degradation of the device. This feedback resistor forms a pole with the input capacitance of the device. For feedback resistor values greater than 10kΩ, this pole degrades the amplifier phase margin. Figure 8-1 shows that to alleviate this problem, add a capacitor (20pF to 50pF) in parallel with the feedback resistor.
