ACPL-C784 - Miniature Isolation Amplifiers

Download the ACPL-C784 datasheet PDF. This datasheet also covers the ACPL-C78A variant, as both devices belong to the same miniature isolation amplifiers family and are provided as variant models within a single manufacturer datasheet.

General Description

The ACPL-C78A/C780/C784 isolation amplifier family was designed for current sensing in electronic motor drives.

In a typical implementation, motor currents flow through an external resistor and the resulting analog voltage drop is sensed by the ACPL-C78A/C780/C784.

ACPL-C78A, ACPL-C780, ACPL-C784 Miniature Isolation Amplifiers Data Sheet Description The ACPL-C78A/C780/C784 isolation amplifier family was designed for current sensing in electronic motor drives. In a typical implementation, motor currents flow through an external resistor and the resulting analog voltage drop is sensed by the ACPL-C78A/C780/C784. A differential output voltage is created on the other side of the ACPL-C78A/ C780/C784 optical isolation barrier. This differential output voltage is proportional to the motor current and can be converted to a single-ended signal by using an op-amp as shown in the recommended application circuit.
