Sensing and Monitoring

consists of a sigma-delta analog-

to-digital converter optically

coupled to a digital-to-analog

converter in a hermetically sealed

package. The products are

capable of operation and storage

over the full military temperature

range and can be purchased as

either commercial product or

with full MIL-PRF-38534 Class H

testing or from the appropriate

DSCC drawing. All devices are

manufactured and tested on a

MIL-PRF-38534 certified line and

are included in the DSCC

Description

The HCPL-7850/7851 is an

isolation amplifier that provides

accurate, electrically isolated and

amplified representations of

voltage and current. When used

with a shunt resistor to monitor

the motor phase current in a high

speed motor drive, the device will

offer superior reliability

compared with the traditional

solutions such as current

transformers and Hall-effect

sensors. The HCPL-7850/7851

• 100 kHz Bandwidth

Qualified Manufacturers List,

QML-38534 for Hybrid

Microcircuits.

A 0.1 F bypass capacitor must be connected between pins 1 and 4 and between pins 5 and 8.

CAUTION: It is advised that normal static precautions be taken in handling and assembly of this

component to prevent damage and/or degradation which may be induced by ESD.
