Instrumentation

zero-driftinstrumentation-amplifierprecisionSOP-8adjustable-gainrail-to-rail-output

TPA1286U-SO1R is a precision zero-drift instrumentation amplifier for low-level differential measurement with gain programmable from 1 V/V to 1000 V/V.

Best for

  • Bridge and sensor interfaces
  • Precision current measurement
  • Industrial data-acquisition front ends

Avoid if

  • The input common-mode voltage approaches the positive supply rail
  • A confirmed lifecycle or compliance declaration is required before release

Check before use

  • Choose a stable, low-drift external RG resistor.
  • Place 0.1 µF bypass capacitors close to each supply pin.
  • Keep RG and REF traces short and use a low-impedance local reference connection.
