CA5420AM

Instrumentation, Op Amps, Buffer Amps Overview

The CA5420AM is a single-channel general-purpose operational amplifier manufactured by Renesas Electronics Corporation. It utilizes BiMOS technology to achieve low input bias current and low supply voltage operation. The device features a gain-bandwidth product of 500 kHz, a slew rate of 0.5 V/µs, and an input offset voltage of 2 mV. It operates with a supply voltage range from 2 V to 20 V and draws 450 µA of supply current. The output provides rail-to-rail swing capabilities. The component is housed in an 8-SOIC package and supports a junction temperature range from -55°C to 125°C.
