OPA4227UA

The OPA4227UA is a high precision, low noise Operational Amplifier combines 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 OPAx228 is optimized for closed-loop gains of 5 or greater and offers higher speed with a slew rate of 10V/µs and a bandwidth of 33MHz. The OPAx227 series operational amplifier is ideal for professional audio equipment. In addition, low quiescent current and low cost make them ideal for portable applications requiring high precision. The OPAx227 series operational amplifier is pin-for-pin replacements for the industry standard OP-27 with substantial improvements across the board.
