AD8230YRZ (ANALOG DEVICES)

The AD8230YRZ is a low drift differential sampling precision Instrumentation Amplifier. Auto-zeroing reduces offset voltage drift to less than 50nV/°C. The AD8230 is well-suited for thermocouple and bridge transducer applications. The AD8230's high CMR of 110dB (minimum) rejects line noise in measurements where the sensor is far from the instrumentation. The 16V 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 3µV 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 to +125°C. Two external resistors are used to program the gain. By using matched external resistors, the gain stability of the AD8230 is much higher than instrumentation amplifiers that use a single resistor to set the gain.
