Application Scenarios & Design Considerations

Single/Dual/Quad, Micropower, Single-Supply, Rail-to-Rail Op Amps

Alternative Part Number

  • AD704ARZ --: Quad low-power op-amp with similar input offset and supply range, pin-compatible in many 14-pin SOIC designs and a common cross for the MAX494.
  • OP497GSZ --: Precision quad op-amp with very low input bias current and low offset, suitable replacement where MAX494 precision is required.
  • LT1014DSW --: Quad precision op-amp with comparable supply voltage and offset performance, widely used as a functional substitute in instrumentation circuits.
  • OPA4277UA --: Quad precision operational amplifier with low offset voltage and low drift, suitable replacement for precision quad op-amp applications.
  • AD8639ARZ --: Quad precision op-amp with rail-to-rail output and low offset, offering comparable performance in a SOIC-14 package.
