Data Sheet
Description
The ACPL-782T isolation amplifier was designed for
voltage and current sensing in electronic motor drives
and battery system monitoring. In a typical implementa-
tion, and motor currents flow through an external resistor
and the resulting analog voltage drop is sensed by the
ACPL-782T. A differential output voltage is created on the
other side of the ACPL-782T 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 ap-
plication circuit. Since common-mode voltage swings
of several hundred volts in tens of nanoseconds are
common in modern switching inverter motor drives, the
ACPL-782T was designed to ignore very high common-
mode transient slew rates (of at least 10 kV/Ps).
The high CMR capability of the ACPL-782T isolation
amplifier provides the precision and stability needed to ac-
curately monitor motor current and DC rail voltage in high
noise motor control environments, 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 conditions. The
ACPL-782T utilizes sigma delta (6') 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 -300E is also available).
