GENERAL DESCRIPTION

The AD8230 is a low drift, differential sampling, precision instrumentation amplifier. Auto-zeroing reduces offset voltage drift to less than 50 nV/°C. The AD8230 is well-suited for thermocouple and bridge transducer applications. The AD8230’s high CMR of 110 dB (minimum) rejects line noise in measurements where the sensor is far from the instrumentation.

The 16 V rail-to-rail, common-mode input range is useful for noisy environments where ground potentials vary by several volts. Low frequency noise is kept to a minimal 3 μV p-p, making the AD8230 perfect for applications requiring the utmost dc precision. Moreover, the AD8230 maintains its high performance over the extended industrial temperature range of −40°C to +125°C.
