Package SOIC-8

Features

  • Single resistor gain setting (1-10000)
  • 50uV low input offset
  • 100 dB high CMRR at G=10
  • 1 nA low input bias current
  • 800 kHz bandwidth at G=10
  • +/-2.3V to +/-18V supply range

Applications

  • Medical ECG/EEG front end
  • Strain gauge bridge amplifier
  • Precision current sensing
  • Industrial process control

The AD620ARZ-REEL7 from Analog Devices is a high-accuracy instrumentation amplifier in SOIC-8. Gain from 1 to 10000 set by a single external resistor: G = (49.4 kOhm / RG) + 1. 50uV max input offset and 100 dB CMRR at G=10 provide excellent DC accuracy for bridge and sensor measurements. 1nA input bias current minimizes error with high-impedance sensors.

Three-op-amp instrumentation amplifier topology. Two input buffer amplifiers provide high input impedance and differential gain. A subtractor stage removes common-mode voltage. The single gain resistor RG sets the differential gain without affecting CMRR. The laser-trimmed thin-film resistors ensure high CMRR and low offset without external trimming.

Pin Name Description
1 RG1 Gain resistor
2 IN- Inverting input
3 IN+ Non-inverting input
4 VS- Negative supply
5 REF Reference (output offset)
6 OUT Output
7 VS+ Positive supply
8 RG2 Gain resistor
  • ECG/EEG front end
  • Strain gauge
  • Current sensing
  • Process control
