Supplier of analog interface components, Avago Technologies announced that it is providing optical isolation amplifiers for current sensing and motor control applications.
The ACPL-7900, ACPL-790A, and ACPL-790B optical isolation amplifiers are ideal for general analogue isolation, solar panel power systems, wind power generation, servo motor drives, industrial inverters and brushless DC motor drives.
ACPL-790B Isolation Amplifiers
The optical isolation amplifier senses the analog voltage drop that results when the current flows via the resistor and implements a motor drive. This enables the isolation amplifier to safely generate a proportional output voltage on the optical isolation barrier’s side.
The isolation amplifiers come in a DIP-8 package and function from a 5 V supply. The 5 V supply is compatible with 3.3 V outputs. According to Avago, the ACPL-790B optical isolation amplifier offers a maximum high gain accuracy of 0.5% and provides a swift response time of 1.6 ms and a bandwidth of 200 kHZ.
