NTE975 & NTE975SM
Integrated Circuit
Operational Amplifier
Description:
The NTE975 and NTE975SM are general purpose operational amplifiers built on a single chip. The
resulting close match and tight thermal coupling gives low offsets and temperature drift as well as fast
recovery from thermal transients.
The unitygain compensation specified makes the circuit stable for all feedback configurations, even
with capacitive loads. However, it is possible to optimize compensation for the best high frequency
performance at any gain. As a comparator, the output can be clamped at any desired level to make
it compatible with logic circuits.

Note 1. For operating at elevated temperatures the devices must be derated based on a maximum
junction to case thermal resistance of +45
C/W, or +150
C/W junction to ambient.
Note 2. For supply voltages less than
15V, the absolute maximum input voltage is equal to the supply
voltage.
Note 3. Continuous short circuit is allow for ambient temperatures to +70
C.
