NTE944 & NTE944M
Integrated Circuit
Programmable Operational Amplifier
Description:
The NTE944 (8–Lead Metal Can) and NTE944M (8–Lead 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–bandwidth product. These devices are truly general purpose operational amplifiers.
Features:
D ±1V to ±18V power supply operation
D 3nA input offset current
D Standby power consumption as low as 500mW
D No frequency compensation required
D Programmable electrical characteristics
D Offset voltage nulling capability
D Can be powered by two flashlight batteries
D Short circuit protection

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