Amplifiers

Instrumentation amplifierPrecision analogLow powerSOIC-8Externally set gain

INA118U/2K5 is a precision, low-power instrumentation amplifier in an SOIC-8 reel package. It uses one external resistor to set gain from 1 to 10000 V/V.

Best for

  • Bridge and transducer signal conditioning
  • Thermocouple and RTD front ends
  • Low-power data-acquisition inputs

Avoid if

  • Inputs cannot be kept within the specified common-mode range
  • A rail-to-rail input stage is required on a low single supply

Check before use

  • Confirm the RG value and its tolerance
  • Drive Ref from a low-impedance node
  • Validate the SOIC-8 footprint and reel requirement
