SINGLE-SUPPLY OPERATIONAL AMPLIFIERS MicroAmplifier?⠓eries

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/s) 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/s 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 and quad versions are available for space savings and per- channel cost reduction. The OPA227 OPA228 OPA2227 and OPA2228 are available in DIP-8 and SO-8 packages. The OPA4227 and OPA4228 are available in DIP-14 and SO-14 packages with standard pin configurations. Operation is specified from 40C to +85C By Texas Instruments
