Application Scenarios & Design Considerations

Single/Dual/Triple/Quad Operational Ampliflers

Alternative Part Number

  • TLC271BCP --: Low-power CMOS op-amp with similar input characteristics and pin-compatible DIP-8 footprint, widely available and cost-effective.
  • LMC662CN --: Dual CMOS op-amp with very low input bias current, close electrical match to the ICL7621 in an 8-pin DIP package.
  • CA3260AE --: Dual BiMOS op-amp offering comparable input impedance and supply range, suitable as a functional replacement in 8-pin DIP.
  • CA3240E --: Dual BiMOS operational amplifier with high input impedance and low bias current, suitable replacement where ICL7621's high-impedance CMOS inputs are required.
  • CA3140E --: High input impedance BiMOS operational amplifier that can replace ICL7621 in circuits where low bias current and wide supply range are required.
