The minimum CMRR performance over the -40°C to +125°C temperature range is >120dB for power supply voltages from ±5V (10V) to ±15V (30V). The series resistors limit the high feed-through currents that can occur in pulse applications when the input dV/dT exceeds the 0.5V/µs slew rate of the amplifier. Without the series resistors, the input can forward-bias the anti-parallel diodes causing current to flow to the output resulting in severe distortion and possible diode failure. Figure 46 provides an example of distortion free large signal response using a 4VP-P input pulse with an input rise time of 1000) reduces input bias current while maintaining good frequency response, low input bias current and low noise. Input bias cancellation circuits provide additional bias current reduction to
