Overview
The AD8230YRZ-REEL7 is a precision instrumentation amplifier produced by Analog Devices Inc. It is designed for low drift and differential sampling applications, making it ideal for thermocouple and bridge transducer measurements. The device features auto-zeroing technology, which reduces offset voltage drift to less than 50 nV/°C. This amplifier is well-suited for environments with significant line noise and varying ground potentials, thanks to its high common-mode rejection ratio (CMR) of 110 dB and a 16 V rail-to-rail common-mode input range. Its low frequency noise of 3 μV p-p ensures high dc precision, making it suitable for applications requiring utmost accuracy.
