HCPL-788J-000E

Instrumentation, Op Amps, Buffer Amps Overview

The HCPL-788J-000E is a single-channel optically isolated amplifier manufactured by Broadcom Limited. It operates on a dual power supply ranging from 4.5 V to 5.5 V and utilizes a 16-pin SOIC surface-mount package with a height of 3.51 mm. The device features an input offset voltage (Vos) of 3 mV and provides a common-mode rejection ratio (CMRR) of 85 dB. It functions within a temperature range of -40°C to +85°C, drawing a typical operating supply current of 20 mA.

Instrumentation, Op Amps, Buffer Amps Feature Summary
