Avago ACPL-790x Precision Isolation Amplifiers

Avago Technologies ACPL-7900, ACPL-790A, and ACPL-790B precision isolation amplifiers are designed for current and voltage sensing in electronic power converters in applications including motor drives and renewable energy systems. The ACPL-7900 (±3% gain tolerance) and ACPL-790A (±1% gain tolerance) are recommended for general applications. The ACPL-790B (±0.5% gain tolerance) is ideal for high-precision applications. These Avago Technologies devices operate from a single 5V supply and provide dynamic performance of 60dB SNR. ACPL-790x isolation amplifiers feature 200 kHz bandwidth and 1.6µs fast response time, allowing these devices to capture transients in short-circuit and overload conditions. These Avago precision isolation amplifiers operate over a -40° C to +105° C temperature range.
