Broadcom ACPL-C870/A/B Optically Isolated Voltage Sensors

Broadcom ACPL-C870/ACPL-C87A/ACPL-C87B Optically Isolated Voltage Sensors are optical isolation amplifiers designed specifically for voltage sensing. The 2V input range and high 1GΩ input impedance makes these Broadcom devices well suited for isolated voltage sensing requirements in electronic power converters applications, including motor drives and renewable energy systems.

ACPL-C87A (±1% gain tolerance) and ACPL-C870 (±3% gain tolerance) are ideal for general applications. For high precision requirements, ACPL-C87B (±0.5% gain tolerance) is ideal. Broadcom ACPL-C870/ACPL-C87A/ACPL-C87B Sensors are optical isolation amplifiers designed specifically for voltage sensing. optical isolation amplifiers operate from a single 5V supply and provide excellent linearity. An active-high shutdown pin is available to reduce the Idd1 current to only 15uA, making these devices suitable for battery-powered and other power-sensitive applications.
