High Precision, Low Noise OPERATIONAL AMPLIFIERS

The OPA227 and OPA228 series op amps combine low noise and wide bandwidth with high precision to make them the ideal choice for applications requiring both ac and preci- sion dc performance. The OPA227 is unity-gain stable and features high slew rate (2.3V/µs) and wide bandwidth (8MHz). The OPA228 is opti- mized 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 OPA227 and OPA228 series op amps are ideal for professional audio equipment. In addition, low quiescent current and low cost make them ideal for portable applica- tions requiring high precision. The OPA227 and OPA228 series op amps are pin-for-pin replacements for the industry standard OP-27 and OP-37 with substantial improvements across the board. The dual channel versions provide higher output current and higher output swing.
