Precision Miniature Isolation Amplifiers
Data Sheet
Description
The ACPL-C79B/C79A/C790 isolation amplifiers were
designed for current and voltage sensing in electronic
power converters in applications including motor drives
and renewable energy systems. In a typical motor drive
implementation, current flows through an external
resistor and the resulting analog voltage drop is sensed
by the isolation amplifier. A differential output voltage
that is proportional to the current is created on the other
side of the optical isolation barrier.
For general applications, the ACPL-C79A (±1% gain
tolerance) and the ACPL-C790 (±3% gain tolerance)
are recommended. For high precision applications, the
ACPL-C79B (±0.5% gain tolerance) can be used. The
product operates from a single 5 V supply and provides
excellent linearity and dynamic performance of 60 dB SNR.
With 200 kHz bandwidth, 1.6 Ps fast response time, the
product captures transients in short circuit and overload
conditions. The high common-mode transient immunity
(15 kV/Ps) of the ACPL-C79B/C79A/C790 provides the
precision and stability needed to accurately monitor
motor current in high noise motor control environments,
providing for smoother control (less “torque ripple”) in
various types of motor control applications.
Combined with superior optical coupling technology, the
ACPL-C79B/C79A/C790 implements sigma-delta (¦')
analog-to-digital converter, chopper stabilized ampli-
fiers, and a fully differential circuit topology to provide
unequaled isolation-mode noise rejection, low offset,
high gain accuracy and stability. This performance is
delivered in a compact, auto-insertable Stretched SO-8
(SSO-8) package that meets worldwide regulatory safety
standards.
