Product Summary
Description
The HCPL-7800 high CMR
isolation amplifier provides a
unique combination of features
ideally suited for motor control
circuit designers. The product
provides the precision and
stability needed to accurately
monitor motor current in highnoise
motor control environments,
providing for smoother
control (less “torque ripple”) in
various types of motor control
applications.
This product paves the way for a
smaller, lighter, easier to produce,
high noise rejection, low cost
solution to motor current
sensing. The product can also be
used for general analog signal
isolation applications requiring
high accuracy, stability and
linearity under similarly severe
noise conditions. For general
HCPL-7800 which exhibits a
part-to-part gain tolerance of
± 5%. For precision applications,
HP offers the HCPL-7800A and
HCPL-7800B, each with part-topart
gain tolerances of ± 1%.
The HCPL-7800 utilizes sigmadelta
(SD) analog-to-digital
converter technology, chopper
stabilized amplifiers, and a fully
differential circuit topology
fabricated using HP’s 1 mm
CMOS IC process. The part also
couples our high-efficiency, highspeed
AlGaAs LED to a highspeed,
noise-shielded detector
