AD8230

16 V Rail-to-Rail, Zero-Drift, Precision Instrumentation Amplifier AD8230 FEATURES Resistor programmable gain range: 101 to 1000 Supply voltage range: ±4 V to ±8 V Rail-to-rail input and output Maintains performance over −40°C to +125°C Excellent ac and dc performance 110 dB minimum CMR @ 60 Hz, G = 10 to 1000 10 μV maximum offset voltage (RTI, ±5 V operation) 50 nV/°C maximum offset drift 20 ppm maximum gain nonlinearity APPLICATIONS Pressure measurements Temperature measurements Strain measurements Automotive diagnostics 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 ...
