Analog Devices Introduces Industry's First Instrumentation Amplifier

The AD8230's low-drift and precision over extended temperature range are ideal for industrial applications.

Analog Devices Inc. introduced the 16-V, zero-drift precision instrumentation amplifier (in-amp). Designed for optimal performance in noisy industrial environments, the AD8230 features the industry's highest common mode input range, maintains low drift, and delivers precise measurements over an extended temperature range. Until now, industrial process control design engineers could only achieve this level of performance by adding resistors around discrete zero-drift operational amplifiers, making it costly and difficult to implement.
In addition to its 16-V common mode input voltage range, the AD8230 is the only solution that maintains better than 50 nV/degree C offset drift over the automotive and extended industrial temperature range of -40 degrees C to +125 degrees C. The AD8230's 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.

The AD8230 is versatile yet simple to use. Two matched external resistors are required to program the gain, offering greater stability over single resistor programmed instrumentation amplifiers.
The AD8230 operates on ±4-V to ±8-V dual supplies, or +8-V to +16-V single supplies, with input and output rail-to-rail capability.

The AD8230 is available now in 8-lead SOIC and is priced at $2.95 in 1,000-piece quantities.
