OP07AZ/883 概述
An operational amplifier (op amp) is a high-gain voltage amplifier with differential inputs and a single-ended output. It is a fundamental building block in analog electronics, used in signal conditioning, filtering, and mathematical operations. The OP07 belongs to the family of precision op amps, which prioritize low offset voltage, low noise, and high stability over bandwidth. In the hierarchy of analog ICs, it sits under linear amplifiers, which are part of the broader category of analog signal processing components.
Key features of the OP07AZ/883 include a low input bias current of 2 nA (typical), a high open-loop gain of 400 V/mV (minimum), and a common-mode rejection ratio (CMRR) of 120 dB (typical). The device operates from dual supplies of ±3 V to ±18 V and is specified over the full military temperature range of -55°C to +125°C. The CDIP-8 package provides hermetic sealing, ensuring reliability in harsh environments.
Technically, the OP07 uses a bipolar process with laser-trimmed thin-film resistors to achieve its low offset voltage. The input stage is a super-beta transistor pair, which reduces input bias current while maintaining high gain. The output stage can drive loads as low as 2 kΩ, and the device is internally compensated for unity-gain stability. The /883 suffix indicates compliance with MIL-STD-883 test methods, including Group A, B, C, and D inspections.
Typical applications include precision voltage references, thermocouple amplifiers, strain-gauge signal conditioning, and active filters. The low offset and drift ensure accurate DC performance, while the wide supply range allows use in both 5V and ±15V systems. The military temperature rating makes it suitable for aerospace and defense electronics.
When designing with the OP07AZ/883, consider the input common-mode range, which extends from -12V to +13V with ±15V supplies. For best performance, use a guard ring around the input pins to minimize leakage currents, and bypass the supply pins with 0.1 µF ceramic capacitors.

设计说明
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.
合规信息
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.
