Analog Devices OP470G Quad Operational Amplifier

Analog Devices OP470G is a high-performance monolithic quad operational amplifier that contains four identical amplifiers in a single package, delivering ultra-low-noise performance suitable for instrumentation and precision signal conditioning. The device provides a very low input-referred voltage noise density of 5 nV/√Hz at 1 kHz (max), a figure that helps it achieve audio- or sensor-front-end clarity and is often compared with the OP27 for similar accuracy. Channel-to-channel matching is a notable strength, which simplifies multi-channel instrumentation and differential configurations; the four amplifiers share common internal characteristics, helping maintain consistent gains and offsets across channels. The OP470G operates from a supply range of ±4.5 V to ±18 V (9–36 V total) and exhibits a power-supply rejection ratio around 5.6 mV/V, contributing to stability in variable supply environments. It is rated for industrial temperatures from -40°C to +85°C, making it well-suited for rugged lab, field, and aerospace-style applications where performance must endure temperature swings. Ideal uses include sensor conditioning, precision active filters, and multi-channel signal conditioning where low noise, tight matching, and reliable operation across the four channels are critical.
