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).
