6MHz, Rail-to-Rail I/O CMOS Operational Amplifier CXAO42157A (single), CXAO42157B (dual) and CXAO42157C (single with shutdown) are low noise, low voltage, and low power operational amplifiers that can

The CXAO42157A (single), CXAO42157B (dual) and CXAO42157C (single with shutdown) are low noise, low voltage, and low power operational amplifiers that can be designed into a wide range of applications. The CXAO42157A/B/C have a high gain-bandwidth product of 6MHz and a slew rate of 3.7V/μs. The CXAO42157C has a power-down disable feature that reduces the supply current to less than 1μA.

The CXAO42157A/B/C are designed to provide optimal performance in low voltage and low noise systems. They provide rail-to-rail output swing into heavy loads. The input common mode voltage range includes ground, and the maximum input offset voltage is 3.5mV for CXAO42157A/B/C. They are specified over the extended industrial temperature range (-40℃ to +125℃). The operating supply range is from 2V to 5.5V.

The CXAO42157A single is available in Green SC70-5, SOT-23-5 and SOIC-8 packages. The CXAO42157B dual is available in Green SOIC-8 and MSOP-8 packages. The CXAO42157C single with shutdown is available in Green SOT-23-6 and SOIC-8 packages.
