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 pro-
portional 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-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,
chopper 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-insert-
able, industry standard 8-pin DIP package that meets
worldwide regulatory safety standards. (A gull-wing
surface mount option #300 is also available).
