ACPL-C78A, ACPL-C780, ACPL-C784

Miniature Isolation Amplifiers

Data Sheet

Description

The ACPL-C78A/C780/C784 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 ACPL-C78A/C780/C784. A differential output

voltage is created on the other side of the ACPL-C78A/

C780/C784 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 common in modern switching

inverter motor drives, the ACPL-C78A/C780/C784 was

designed to ignore very high common-mode transient

slew rates (of at least 10 kV/μs).

The high CMR capability of the ACPL-C78A/C780/C784

isolation amplifier 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.

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 applications, we recommend the ACPL-C780 (gain

tolerance of ±3%) and the ACPL-C784 (gain tolerance of

±5%). For precision applications Avago Technologies offers

the ACPL-C78A with part-to-part gain tolerance of ±1%.

The ACPL-C78A/C780/C784 utilizes sigma-delta (∑-∆) an-

alog-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-insertable,

Stretched SO-8 (SSO-8) package that meets worldwide

regulatory safety standards.
