ACPL-C870-000E

The ACPL-C870-000E is a precision optically isolated voltage sensor in 8 pin SSO package. This voltage sensor is an optical isolation amplifier designed specifically for voltage sensing. Its 2V input range and high 1Gohm input impedance makes it well suited for isolated voltage sensing requirements in electronic power converters applications. A resistive voltage divider is used to scale DC link voltage to suit input range of voltage sensor. A differential output voltage that is proportional to input voltage is created on other side of optical isolation barrier. The ACPL-C870 operates from single 5V supply and provides excellent linearity. An active high shutdown pin is available which reduces IDD1 current to only 15mA making them suitable for battery powered and other power sensitive applications. The high common mode transient immunity (15KV/µs) of ACPL-C870 provides precision and stability needed to accurately monitor DC link voltage in high noise environments.
