Operational Amplifier
8-PIN DIP
To order >>> NTE975SM
Description:
The NTE975 and NTE975SM are general purpose operational amplifiers built on a single chip. The resulting close match and tight thermal coupling gives low offsets and temperature drift as well as fast recovery from thermal transients.
The unity-gain compensation specified makes the circuit stable for all feedback configurations, even with capacitive loads. However, it is possible to optimize compensation for the best high frequency performance at any gain. As a comparator, the output can be clamped at any desired level to make it compatible with logic circuits.
Features:
- Available in 8-Lead Mini DIP (NTE975) and Surface Mount, SIOC-8 (NTE975SM)
- Frequency Compensation with a Single 30pF Capacitor
- Operation From ±5V to ±20V
- Low Current Drain: 1.8mA @ ±20V
- Continuous Short-Circuit Protection
- Operation as a Comparator with Differential Inputs as High as ±30V
- No Latch-Up when Common Mode Range is Exceeded

| Note 1. | For operating at elevated temperatures the devices must be derated based on a maximum junction to case thermal resistance of +45°C/W, or +150°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. | Continuous short circuit is allowed for ambient temperatures to +70°C. |

| Note 4. | The input common-mode voltage or either input signal voltage should not be allowed to go negative by more than 0.3V. The upper end of the common-mode voltage range is VCC-1.7V, but either or both inputs can go to +32V without damage. |
| Note 5. | Short circuit from the output to VCC can cause excessive heating and eventual destruction. Destructive dissipation can result from simultaneous shorts on all amplifiers. |
