Optical Isolation Amplifiers
Broadcom Inc.Request Info
Avago Technologies has announced precision optical isolation amplifiers
for motor control and current-sensing applications. The ACPL-790B, ACPL-790A and
ACPL-7900 devices improve the accuracy and response times of the company’s
isolation amplifiers while addressing compact applications with a smaller footprint
package. They are suitable for current and voltage sensing in AC and brushless DC
motor drives, industrial inverters, servo motor drives, wind power generation, solar
panel power systems and general analog isolation. As current flows through the external
resistor in a motor drive implementation, the resulting analog voltage drop is sensed
by the isolation amplifiers, and they allow a proportional output voltage to be
created safely on the other side of the optical isolation barrier.
