HCPL-7800A Datasheet PDF (Isolation Amplifer)

HCPL-7800A - Isolation Amplifer

Description

The HCPL-7800(A) 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 HCPL-7800(A).

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, 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 = 1000 V.
Compact, Auto-Insertable Standard 8-pin DIP Pack- age.
0.00025 V/V/°C.

HCPL-7800A/HCPL-7800 Isolation Amplifer Datasheet Lead (Pb) Free RoHS 6 fully compliant RoHS 6 fully compliant options available; -xxxE denotes a lead-free product Description The HCPL-7800(A) 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 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.
