ACPL-C79B-500E

The ACPL-C79B-500E is a precision miniature Isolation Amplifier designed for current and voltage sensing in electronic power converters. It operates from a single 5V supply and provides excellent linearity and dynamic performance of 60dB SNR. The amplifier with 200kHz bandwidth, 1.6µs fast response time, the product captures transients in short-circuit and overload conditions. The high common-mode transient immunity provides the precision and stability needed to accurately monitor motor current in high noise motor control environments, providing for smoother control in various types of motor control applications. In a typical motor drive implementation, current flows through an external resistor and the resulting analogue voltage drop is sensed by the isolation amplifier.

• Advanced sigma-delta A/D converter technology
