Analog Devices has introduced the industry's first precision difference amplifier to maintain excellent Common-Mode Rejection Ratio (CMRR) that exceeds 90dB at voltages up to ±600 V. Designed for applications such as motor control, process control and power supplies, the AD8479 enables accurate measurements of currents in the presence of voltage fluctuations as large as ±600 V without additional complex signal conditioning components. The AD8479 guarantees to reject ±200V with ±5V power supplies. The AD8479 offers cost-effective isolation and can replace more costly devices in applications that do not require galvanic isolation. With higher than 90 dB CMRR, 130 kHz bandwidth, 2M ohm differential input impedance, within 0.02% gain error and 5ppm/°C gain drift, the AD8479 offers precision over a wide range of common-mode voltages and frequencies. It operates over an extended temperature range of -40°C to +125°C.
