AD8230YRZ-REEL7

AD8230YRZ-REEL7 is a low drift, differential sampling, precision instrumentation amplifier. Auto-zeroing reduces offset voltage drift to less than 50nV/°C. It is well-suited for thermocouple and bridge transducer applications. This device’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 device perfect for applications requiring the utmost dc precision. It is versatile yet simple to use. Its auto-zeroing topology significantly minimizes the input and output transients typical of commutating or chopper instrumentation amplifiers. It is used in applications such as pressure measurements, temperature measurements, strain measurements, automotive diagnostics.
