Precision Operational Amplifier
(OP Amp)
Description:
The NTE938 and NTE938M operational amplifiers provide high input impedance, low input offsets
and temperature drifts, and low noise. This series of amplifiers is particularly useful for applications
where high–accuracy and low–drift performance are essential. In addition, high–speed performance
may be improved by employing feed–forward compensation techniques to maximize slew rate with-
out compromising other performance criteria.
The NTE938 and NTE938M offer extremely low input offset voltage and drift specifications allowing
usage in even the most critical applications without external offset nulling.

Note 1. For supply voltages less than ±15V, the maximum input voltage is equal to the supply voltage.
Note 2. The inputs are shunted with back–to–back diodes for over–voltage protection. Therefore,
excessive current will flow if a differential input voltage in excess of 1.0V is applied between
the inputs unless some limiting resistance is used.
