ACPL-C87A
Description
The ACPL-C87B/C87A/C870 voltage sensors are optical isolation amplifiers designed specifically for voltage sensing. Its 2 V input range and high 1 G input impedance, makes it well suited for isolated voltage sensing requirements in electronic power converters applications including motor drives and renewable energy systems. In a typical voltage sensing implementation, a resistive voltage divider is used to scale the DC-link voltage to suit the input range of the voltage sensor. A differential output voltage that is proportional to the input voltage is created on the other side of the optical isolation barrier.
For general applications, the ACPL-C87A (±1% gain tolerance) and the ACPL-C870 (±3% gain tolerance) are remended. For high precision requirements, the ACPL-C87B (±0.5% gain tolerance) can be used. The ACPL-C87B/C87A/C870 family operates from a single 5 V supply and provides excellent linearity. An active-high shutdown pin is available which reduces the IDD1 current...
