Low power: 330 μA maximum quiescent current
Rail-to-rail output
Low noise and distortion
8 nV/√Hz maximum input voltage noise at 1 kHz
0.15 μV p-p RTI noise (G = 100)
0.5 ppm nonlinearity with 2 kΩ load (G = 1)
Excellent ac specifications
80 dB minimum CMRR at 7 kHz (G = 1)
2.2 MHz bandwidth (G = 1)
High precision dc performance (AD8422BRZ)
150 dB minimum CMRR (G = 1000)
0.04% maximum gain error (G = 1000)
0.3 μV/°C maximum input offset drift
0.5 nA maximum input bias current
Wide supply range
3.6 V to 36 V single supply
±1.8 V to ±18 V dual supply
Input overvoltage protection: 40 V from opposite supply
Gain range: 1 to 1000
Смещение 0.3 мкВ на градус, 0.15 мкВ шумы - вполне неплохо. (Что такое RTI noise?)
