| 2 | NTE924 | Integrated Circuit Voltage Follower / Operational Amplifier NTE924 & NTE924M Integrated Circuit Voltage Follower, Operational Amplifier Description: The NTE924 and NTE924M are monolithic operational amplifiers internally connected as unity–gain non–inverting amplifiers. These devices use super–gain transistors in the input stage to get low bias current without sacrificing speed. Directly interchangeable with the NTE909 and NTE941 |
