Q
Does the OP16 op-amp slew rate response fall as the differential signal falls?(ie diff signals below 50mV). Do you have a graph for this?
A
The slew rate for the device is 25V / us, for a Closed loop gain of 1 and ModelN, with +-15V power supplies.
But the transient response graph on page 9 of the datasheet gives you an idea
of the response of this device at low input signal.
