Avago has announced three new precision isolation amplifiers with increased accuracy, bandwidth and high insulation made possible by proprietary optical isolation technology.
Based on sigma-delta analog-to-digital converters and chopper stabilised amplifiers, the new isolation amplifiers feature high gain accuracy, low temperature drift, 3,3 V/5 V output supply operation and a wide -40°C to +105°C operating temperature range. These features are delivered in a stretched SO-8 package that has a footprint 30% smaller than the standard DIP-8 package.
The series is implemented with a fully differential circuit topology with a gain accuracy of ±0,5% (ACPL-C79B), ±1% (ACPL-C79A), and ±3% (ACPL-C790). Normalised gain drift is 50 ppm/°C. With a 200 kHz bandwidth and 1,6 μs response time, the ACPL-C79x captures transients during short circuit and overload conditions. Operating from a single 5 V supply, the isolation amplifier series features nonlinearity of 0,05% and SNR of 60 dB.
The amplifiers’ high common-mode transient immunity of 15 kV/μs provides the precision and stability needed to accurately monitor current in high-noise motor control environments. This ensures smoother control with less torque ripple in many motor control applications. Widely used for motor phase and rail current sensing, servo motor drive, switching power supply feedback isolation, DC link voltage monitoring, inverter current sensing and switching power supply feedback isolation, the ACPL-C97x targets industrial automation and instrumentation, renewable energy and HVAC markets.
