Analog Devices Press Release - March 9, 2011
Zero Drift and High Bandwidth - Analog Devices’ AD8218 offers users a flexible, high voltage, zero-drift current-sense amplifier that features industry-leading performance and value.
NORWOOD, Mass.--(BUSINESS WIRE)-- Analog Devices, Inc. (ADI), a world leader in semiconductors for high-performance signal processing applications and leading supplier of signal conditioning technology, released for general availability today the newest addition to its popular current-sense-amplifier product line. The AD8218 zero-drift, bi-directional current-sense amplifier offers design engineers a precision current-sense amplifier with the unique combination of high bandwidth and the lowest drift currently available in the market in a low-cost package. Using a proprietary CMOS process, the AD8218 features a zero-drift core that provides an offset drift of ± 100n V/°C over a −40 °C to +125 °C temperature range, while maintaining a typical small signal bandwidth of 500 kHz.
Designed to operate with a wide variety of A/D converters, the AD8218 is designed into numerous high-side current-sensing signal chains, including base station, industrial motor control and computer power management applications. Other precision zero-drift current sense amplifiers in the product family include the AD8217 high resolution, zero-drift current shunt monitor at http://www.analog.com/AD8217 and the AD8219 zero-drift, unidirectional current shunt monitor at http://www.analog.com/AD8219.
