OPAx323 Zero-Cross Operational Amplifiers

Texas Instruments OPAx323 Zero-Cross Operational Amplifiers (Op Amps) are single (OPA323), dual (OPA2323), and quad-channel (OPA4323), low-voltage (1.7V to 5.5V), high-bandwidth (20MHz) op amps with a zero-crossover input stage and a rail-to-rail output stage. The zero-crossover input stage enables OPAx323 to achieve high linearity and low distortion for input signals with rail-to-rail swing typical in ADC driver applications. The gain bandwidth of 20MHz provides a fast settling response for ADC sampling speeds between 0.5MSPS and 5MSPS, depending on the settling performance required. OPAx323 is well-optimized for power savings as it consumes just 1.6mA of typical quiescent current.
