Overview

The ACPL-C87B-000E is an optical isolation amplifier specifically designed for high-precision voltage sensing in power electronic systems. It utilizes advanced Sigma-Delta modulation technology to convert a 0V to 2V analog input into a differential output, providing safe galvanic isolation between high-voltage rails and low-voltage controllers.

Why Choose This Part

The device offers a high 0.5 percent gain accuracy and 15 kV/microsecond common-mode transient immunity, ensuring reliable measurements in high-switching-noise environments. Its active-high shutdown pin reduces current consumption to just 15 microamps, making it suitable for power-sensitive standby applications.

Applications

Isolated DC-Bus Voltage Sensing
Monitoring high-voltage DC links in solar inverters and wind turbine power converters.
Motor Drive Feedback
Providing isolated phase voltage or DC bus feedback in AC and servo motor drives for precise control loops.
EV Powertrain Monitoring
Measuring battery pack voltages and power distribution levels in electric vehicle charging and traction systems.
Industrial Data Acquisition
Interfacing analog sensors to digital controllers in noisy industrial environments requiring high common-mode rejection.

Getting Started

Designers should implement a high-side floating power supply between 3V and 5.5V for the input stage and use a precision resistor divider to scale the target voltage into the 0V to 2V linear range. Evaluation can be performed using standard SO-8 breakout boards, ensuring that creepage and clearance distances are maintained for high-voltage safety requirements.
