ACPL-C87AT-500E

The ACPL-C87AT isolation sensors utilize superior optical coupling technology, with sigma-delta (S-D) analog-to-digital converter, chopper stabilized amplifiers, and a fully differential circuit topology to provide unequaled isolation-mode noise rejection, low offset, high gain accuracy and stability. ACPL-C87AT (±1% gain tolerance) and ACPL-C87BT (±0.5% gain tolerance) are designed for high precision DC voltage sensing in electronic motor drives, DC/DC and AC/DC converter and battery monitoring system. The ACPL-C87AT features high input impedance and operate with full span of analog input voltage up to 2.46 V. The shutdown feature provides power saving and can be controlled from external source, such as microprocessor.
