LT1920IS8#PBF

LT1920 is a low power, precision instrumentation amplifier that requires only one external resistor to set gains of 1 to 10,000. Low input bias currents of 2nA max are achieved with the use of superbeta processing. The output can handle capacitive loads up to 1000pF in any gain configuration while the inputs are ESD protected upto 13kV (human body). This device with two external 5k resistors passes the IEC 1000-4-2 level 4 specification. It is widely used in application such as bridge amplifiers, strain gauge amplifiers, thermocouple amplifiers, differential to single-ended converters, medical instrumentation etc.
