HCPL-7800A/HCPL-7800

Isolation Amplifer

Datasheet

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. Since common-mode voltage swings

of several hundred volts in tens of nanoseconds are com-

mon in modern switching inverter motor drives, the HCPL-

7800(A) was designed to ignore very high common-mode

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

The high CMR capability of the HCPL-7800(A) 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-7800

(gain tolerance of ±3%). For precision applications Avago

Technologies offers the HCPL-7800A with part-to-part

gain tolerance of ±1%. The HCPL-7800(A) utilizes sigma

delta (Σ−∆) analog-to-digital converter technology, chop-

per stabilized amplifiers, and a fully differential circuit

topology.

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 worldwide

regulatory safety standards. (A gull-wing surface mount

option #300 is also available).
