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
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
Qualified Manufacturers List,
QML-38534 for Hybrid
Microcircuits.
