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 the NTE941 series in voltage follower applications, these devices have internal frequency compensation and provision for offset balancing.
Features:
- Available in 8-Lead DIP (NTE924M) and 8-Lead Metal Can (NTE924) Packages
- Input Current: 10nA Max Over Temperature
- Small Signal Bandwidth: 20MHz
- Slew Rate: 30V/µs
- Supply Voltage Range: ±:5V to ±18V

| Note 1. | For operating at elevated temperatures, the NTE924 must be derated based on a thermal resistanced 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 2. | For supply voltages less than ±15V, the absolute maximum input voltage is equal to the supply voltage. |
| Note 3. | Contimuous short-circuit is allowed for case temperatures to +70°C or +55°C ambient temperature. It is necessary to insert a resistor greater than 2k Ohm in series with the input when the amplifier is driven from low impedance sources to prevent damage when the output is shorted. RS = 5k min, 14k typical is recommended for dynamic stability in all applications. |
