The OPA4227PA is a quad Operational Amplifier combine low noise and wide bandwidth with high precision to make them the ideal choice for applications requiring both AC and precision DC performance. The OPAx227 is unity-gain stable and features high slew rate (2.3V/μs) and wide bandwidth (8MHz). The OPAx227 series operational amplifier is pin-for-pin replacements for the industry standard OP-27 and OP-37 with substantial improvements across the board.
3nV/√Hz Low noise
5μs Settling time (significant improvement over OP-27)
