OP90ARC/883C 概要
An operational amplifier (op amp) is a high-gain voltage amplifier with differential inputs and a single-ended output, used in signal conditioning, filtering, and mathematical operations. The OP90 belongs to the family of micropower op amps, which are optimized for low quiescent current while maintaining adequate bandwidth and precision. This category sits within linear amplifiers, which are fundamental building blocks in analog signal processing chains.
Key features of the OP90ARC/883C include its wide supply range, low supply current, and high precision. The device operates from a single supply as low as 1.6 V, enabling use in low-voltage systems. Its micropower design ensures minimal power drain, extending battery life in portable devices. The 883C suffix indicates compliance with MIL-STD-883, a military standard for microcircuits, ensuring high reliability and extended temperature range operation.
Technically, the OP90 uses a bipolar process with a precision input stage that provides low offset voltage and drift. The amplifier is internally compensated for unity-gain stability, simplifying design. Its output stage can swing close to the rails, maximizing dynamic range in single-supply applications. The device also features low input bias current, making it suitable for high-impedance sensor interfaces.
Typical applications include battery monitoring, portable medical devices, sensor signal conditioning, and industrial control systems. The wide supply range and low power make it versatile for both 3 V and 5 V systems, as well as industrial 24 V rails. The military-grade version ensures operation in harsh environments.
When designing with the OP90ARC/883C, consider its bandwidth and slew rate limitations for high-frequency applications. For precision DC applications, the low offset and drift are advantageous. Proper decoupling and layout are essential to maintain performance.

設計ノート
The OP90ARC/883C operates from a single supply of 1.6 V to 36 V or dual supplies of ±0.8 V to ±18 V. Ensure the supply voltage is within these limits to avoid damage. For battery-powered applications, the low supply current helps extend battery life, but consider the load current and output drive capability.
For optimal performance, place decoupling capacitors (0.1 µF and 10 µF) close to the V+ and V- pins. Use a ground plane to minimize noise and ensure stable operation. The CLCC package has exposed pads; ensure proper soldering and thermal relief for reliable connections.
Avoid exceeding the absolute maximum supply voltage of 36 V. Also, ensure the input voltages do not exceed the supply rails. The OP90 is not a rail-to-rail input op amp, so keep inputs within the common-mode range. For high-impedance sources, the input bias current may cause offset errors; use a resistor in the feedback path to compensate.
