Overview

The ACPL-C87BT-000E Automotive isolation amplifier uses superior optical coupling technology with sigma-delta (Σ−Δ) analog-to-digital converters, chopper-stabilized amplifiers, and a fully differential circuit topology to provide unmatched isolation mode noise suppression, low offset, and high efficiency. High gain accuracy and stability The ACPL-C87BT (± 0.5% gain tolerance) is designed for high-precision DC voltage detection in electronic motor drivers, DC/DC and AC/DC converters, and battery monitoring systems. The ACPL-C87BT has a high input impedance and can operate at a full range of analog input voltages up to 2.46V. The shutdown function provides power saving and can be controlled by an external signal source, such as a microprocessor.
