NTE924 Datasheet, PDF (1/3 Pages) NTE Electronics – 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 series in
voltage follower applications, these devices have internal frequency compensation and provision for
offset balancing.

Note 1. The NTE924M is a discontinued device and no longer available.
Note 2. For operating at elevated temperatures, the NTE924 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 NTE924M is +100°C/W, junction–to–ambient.
Note 3. For supply voltages less than ±15V, the absolute maximum input voltage is equal to the supply
voltage.
Note 4. Continuous short–circuit is allowed for case temperatures to +70°C or +55°C ambient tem-
perature. It is necessary to insert a resistor greater than 2kΩ in series with the input when
the amplifier is driven from low impedance sources to prevent damage when the output is
shorted. R_S = 5k min, 14k typical is recommended for dynamic stability in all applications.
