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 o perational amplifiers. A s ingle external master b ias current setting r esistor programs the input b ias c urrent, i nput o ffset c urrent, quiescent power c onsumption, s lew r ate, i nput n oise, a nd t he gain–bandwidth product. These devices are truly general purpose operational amplifiers.
