Application Scenarios & Design Considerations

Low Noise, Low Distortion Instrumentation Amplifier 16-PDIP

Alternative Part Number

  • AD625KNZ --: Instrumentation amplifier with similar low-noise, high-gain performance and pin-compatible DIP package, a well-established alternative to the INA103.
  • INA128PA --: TI instrumentation amplifier with comparable gain range and low offset, though from a different series than the INA103.
  • LT1167CN8 --: Low-noise instrumentation amplifier offering similar functionality and DIP-8 footprint, suitable as a functional substitute.
  • AD620ANZ --: Widely used low-noise instrumentation amplifier in DIP package, suitable replacement for many INA103 applications with lower cost and broad availability.
