ACPL-785E Datasheet Hermetically Sealed Analog Isolation Amplifier

Manufacturer: Broadcom

General Description

The HCPL-7850, HCPL-7851, and ACPL-785E are isolation amplifiers that provide accurate, electrically isolated and amplified representations of voltage and current.

When used with a shunt resistor to monitor the motor phase current in a high-speed motor drive, the device offers superior reliability compared with the traditional solutions such as current transformers and Hall-effect sensors.

These devices consist of a sigma-delta analog-to-digital converter optically coupled to a digital-to-analog converter in a hermetically sealed package.
