Design Notes
For optimal performance, place a 0.1 µF ceramic capacitor close to each supply pin (V+ and V-) to decouple high-frequency noise. Use a ground plane to minimize noise pickup. For high-impedance inputs, add a guard ring around pins 2 and 3 to reduce leakage currents, especially in humid environments.
The OP07AZ/883 is specified for -55°C to +125°C. In high-temperature applications, ensure adequate airflow or heatsinking to keep the junction temperature within limits. The hermetic package has a thermal resistance of approximately 100°C/W (theta_JA), so power dissipation should be limited to avoid exceeding the maximum junction temperature.
Do not exceed the absolute maximum supply voltage of ±22V. The input common-mode range is limited to ±13V with ±15V supplies; exceeding this may cause phase reversal. For offset nulling, connect a 10 kΩ potentiometer between pins 1 and 5 with the wiper to V+. Ensure the potentiometer is of good quality to avoid introducing thermal drift.
Compliance Information
The OP07AZ/883 is a military-grade hermetic package, which typically contains lead-based solder and is exempt from RoHS. MIL-STD-883 compliance is confirmed.
