Zero-drift instrumentation amplifier operates at 16 V

9 March 2005 Analogue, Mixed Signal, LSI

Claimed to be the industry's first 16-V zero-drift precision instrumentation amplifier, Analog Devices' AD8230 chip is designed for optimal performance in noisy industrial environments. It features the industry's highest common mode input range, maintains low drift, and delivers precise measurements over an extended temperature range, says ADI. Until now, industrial process control design engineers could only achieve this level of performance by adding resistors around discrete zero-drift operational amplifiers - costly and difficult to implement. With this instrumentation amp, industrial systems designers obtain the benefits of an integrated, cost-effective solution for instrumentation environments such as precision temperature and bridge transducer interface applications where ground potentials vary by several volts. In addition to its wide 16 V common mode input voltage range, the AD8230 maintains better than 50 nV/°C offset drift over -40 to +125°C. High CMRR of 110 dB (min) rejects line noise in measurements where the sensor is far from the instrumentation or when it exhibits DC offset change over temperature.
