Application Scenarios & Design Considerations

10MHz/ Rail-to-Rail Input and Output Op Amp in SOT-23

Alternative Part Number

  • OPA350EA/250 --: Rail-to-rail CMOS op-amp in SOT-23-5 with similar bandwidth and low input bias current, a common drop-in for the LT1797 in low-power signal chains.
  • MAX4162EUK+T --: Micropower rail-to-rail op-amp in SOT-23-5 offering comparable supply current and offset performance for portable applications.
  • AD8605ARTZ-REEL7 --: Low-noise, low-offset CMOS op-amp in SOT-23-5 with rail-to-rail I/O, suitable where the LT1797's precision and low power are required.
  • OPA350EA --: Rail-to-rail CMOS op-amp in SOT-23-5 with similar bandwidth and low input bias current, a common drop-in for the LT1797 in low-power signal conditioning.
  • MAX4162EUK --: Micropower rail-to-rail op-amp in 5-pin SOT-23 with comparable supply current and offset, suitable replacement where the LT1797 is used for low-power buffering.
  • AD8605ARTZ --: Low-noise, low-power CMOS rail-to-rail op-amp in SOT-23-5 with similar gain-bandwidth and supply range, a solid functional substitute for the LT1797IS5.
  • MAX4165EUK+T --: Low-power rail-to-rail op-amp in 5-pin SOT-23, comparable supply range and output drive, good functional substitute.
