XR620A Instrumentation Amplifier FEATURES General Description 2.3V to 18V supply voltage range Gain range of 1 to 10,000 The XR620A is a low power, general purpose instrumentation amplifier Gain set with one external resistor with a gain range of 1 to 10,000. The XR620A is offered in 8-lead SOIC or 125V maximum input offset voltage DIP packages and requires only one external gain setting resistor making 0.1V/C input offset drift it smaller and easier to implement than discrete, 3-amp designs. 700kHz bandwidth at G = 1 While consuming only 2.2mA of supply current, the XR620A offers a low 1.2V/s slew rate 6.6nV/Hz input voltage noise and 0.2Vpp noise from 0.1Hz to 10Hz. 90dB minimum CMRR at G = 10 2.2mA maximum supply current The XR620A offers a low input offset voltage of 125V that only varies 6.6nV/Hz input voltage noise 0.1V/C over its operating temperature range of -40C to +85C. The 70nV/Hz output voltage noise XR620A also features 50ppm maximum nonlinearity. These features 0.2V input noise (0.1Hz to 10Hz) make it well suited for use in data acquisition systems. pp DIP-8 or Pb-free SOIC-8 APPLICATIONS Bridge amplifier Weigh scales Thermocouple amplifier ECG and medical instrumentation MRI (Magnetic Resonance Imaging) Patient monitors Transducer interface Data acquisition systems Strain gauge amplifier Industrial process controls Ordering Information - back page Competitive Plot Typical Application 3 2 +V S Competitor A Input 1 2 0 1 7 -1 XR620A R V G OUT XR620A 6 -2 5 -3 8 Load 4 G = 1 -4 Reference 3 V = 15V S +Input -5 V = 0.2V OUT pp V S -6 R = 2k L -7 To Power 0.0001 0.001 0.01 0.1 1 10 Supply Ground Frequency (MHz) Thermocouple Amplifier 2013-2015 Exar Corporation 1 / 15 exar.com/XR620A Rev 1B Normalized Gain (dB)XR620A Absolute Maximum Ratings Operating Conditions Supply Voltage Range .......................2.3V to 18V (4.6V to 36V) Stresses beyond the limits listed below may cause permanent damage to the device.
