HCPL-7840

Isolation Amplifier

Data Sheet

Lead (Pb) Free

RoHS 6 fully

compliant

RoHS 6 fully compliant options available;

-xxxE denotes a lead-free product

Description

The HCPL-7840 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-7840. A differential output voltage is created on

the other side of the HCPL-7840 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. Since common-mode voltage swings

of several hundred volts in tens of nanoseconds are

common in modern switching inverter motor drives, the

HCPL-7840 was designed to ignore very high common-

mode transient slew rates (of at least 10 kV/μs).

The high CMR capability of the HCPL-7840 isolation

amplifier provides the precision and stability needed to

accurately monitor motor current in high noise motor

control environ-ments, providing for smoother control

(less “torque ripple”) in various types of motor control

applications.

The product can also be used for general analog signal

isolation applications requiring high accuracy, stability,

and linearity under similarly severe noise con-ditions. For

general applications, we recommend the HCPL-7840 (gain

tolerance of ± 5%). The HCPL-7840 utilizes sigma delta

(∑-Δ) analog-to-digital converter technology, chopper

stabilized amplifiers, and a fully differential circuit topol-

ogy fabricated using Avago’s 0.8 μm CMOS IC process.

Together, these 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 world-

wide regulatory safety standards. (A gull-wing surface

mount option #300 is also available).
