Product Overview
AD8420 is a low cost, micropower, wide supply range, instrumentation amplifier with a rail-to-rail output and a novel architecture that allows for extremely flexible design. It is optimized to amplify small differential voltages in the presence of large common-mode signals. The AD8420 is based on an indirect current feedback architecture that gives it an excellent input common-mode range. Unlike conventional instrumentation amplifiers, the AD8420 can easily amplify signals at or even slightly below ground without requiring dual supplies. The AD8420 has rail-to-rail output, and the output voltage swing is completely independent of the input common-mode voltage. Single-supply operation, micropower current consumption, and rail-to-rail output swing make the AD8420 ideal for battery- powered applications. Typical application includes bridge amplifiers, pressure measurement, medical instrumentation, portable data acquisition and multichannel systems.
- Maximum supply current is 90µA max and minimum CMRR of 100dB
- Drives heavy capacitive loads: ~700pF
- Input voltage range goes below ground gain set with 2 external resistors
- Can achieve low gain drift at any gain
- Very wide power supply range: 2.7V to 36V single supply and ±2.7V to ±18V dual supply
- 2.5KHz bandwidth (G = 100) and input voltage noise of 55nV/√Hz
- High DC precision: maximum offset voltage is 125µV and maximum offset drift is 1µV/°C
- Maximum differential input voltage is ±1V
- 8 lead MSOP package
- Operating temperature range from -40°C to 85°C
