NTE944 & NTE944M
Integrated Circuit
Programmable Operational Amplifier
Description:
The NTE944 (8鈥揕ead Metal Can) and NTE944M (8鈥揕ead MiniDIP) are extremely versatile program-
mable monolithic operational amplifiers. A single external master bias current setting resistor programs
the input bias current, input offset current, quiescent power consumption, slew rate, input noise, and the
gain鈥揵andwidth product. These devices are truly general purpose operational amplifiers.

Note 1. The maximum junction temperature of the NTE944 is 100擄C. For operating at elevated tem-
peratures, the NTE944 must be derated based on a thermal resistance of 150擄C/W junction
to ambient, or 45擄C/W junction to case. The thermal resistance of the NTE944M is +125擄C/W.
Note 2. For supply voltages less than
鹵15V,
the absolute maximum input voltage is equal to the supply
voltage.
