Rail-to-rail output swing
Input voltage range extends 150 mV below ground
(single supply)
Low power, 550 µA maximum supply current
Gain set with one external resistor
Gain range: 1 to 1000
High accuracy dc performance
0.10% gain accuracy (G = 1)
0.35% gain accuracy (G > 1)
Noise: 35 nV/√Hz RTI noise at 1 kHz
Excellent dynamic specifications
800 kHz bandwidth (G = 1)
20 µs settling time to 0.01% (G = 10) The AD623 is an integrated, single-or dual-supply instrumentation
amplifier that delivers rail-to-rail output swing using supply
voltages from 3 V to 12 V. The AD623 offers superior user
flexibility by allowing single gain set resistor programming and by
conforming to the 8-lead industry standard pinout configuration.
With no external resistor, the AD623 is configured for unity
gain (G = 1), and with an external resistor, the AD623 can be …
