ACPL-C78A - Miniature Isolation Amplifiers

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.

Features

  • deliver unequaled isolationmode noise rejection, as well as excellent offset and gain accuracy and stability over time and temperature. This performance is delivered in a compact, auto-insertable, Stretched SO-8 (SSO-8) package that meets worldwide regulatory safety standards. Features.
  • 15 kV/µs Common-Mode Rejection at VCM = 1000 V.
  • Compact, Auto-Insertable Stretched SO-8 Package.
  • 0.00025 V/V/°C Gain Drift vs. Temperature.
  • 0.3 mV Input Offset Voltage.

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.
