15 August 2012 ADI has low power instrumentation amp with zero drift accuracy Amplifier combines power efficiency with zero drift accuracy Analog Devices' new AD8237 zero drift precision instrumentation amplifier has been optimised to offer a power efficient solution for precision signal and sensor conditioning at a competitive price. The module features a low input offset drift (< 0.3µV/ºC) and an 'industry leading' input signal range that extends 300mV beyond the supply rails. Combined with a maximum gain error and drift of 0.005% and 0.5ppm/°C respectively, and a common mode rejection ratio of 114dB, the device is said to offer an unmatched level of precision measurement, even at low gain. With a low quiescent supply current of just over 100µA, the amplifier is well suited for signal conditioning bridge, temperature and other similar sensors used in low power designs. Target applications include portable and battery powered healthcare, consumer and precision instrumentation equipment such as infusion pumps, mobile blood pressure monitors, 4 to 20mA sensors, gaming peripherals and consumer weigh scales.
