HCPL-7800 - Isolation Amplifer

Download the HCPL-7800 datasheet PDF. This datasheet also covers the HCPL-7800A variant, as both devices belong to the same isolation amplifer family and are provided as variant models within a single manufacturer datasheet.

Description

The Broadcom® HCPL-7800A/HCPL-7800 (hereinafter referred to as HCPL-7800(A)), isolation amplifier family is designed for current sensing in electronic motor drives.

Features

  • deliver unequaled isolation-mode 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, industry standard 8-pin DIP package that meets worldwide regulatory safety standards. (A gull-wing surface mount option #300 is also available). Features.
  • 15 kV/µs common-mode rejection at VCM = 1000V.
  • Compact, auto-insertable standard 8-pin DIP package.
  • 0.00025-V/V/°C gain drift vs. te.

HCPL-7800A/HCPL-7800 Isolation Amplifer Data Sheet Description The Broadcom® HCPL-7800A/HCPL-7800 (hereinafter referred to as HCPL-7800(A)), isolation amplifier family is 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 HCPL-7800(A). A differential output voltage is created on the other side of the HCPL-7800(A) 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.
