DESCRIPTION

The OPA2227 operational amplifier combines low noise and wide bandwidth with high precision to make it the

ideal choice for applications requiring both ac and precision dc performance.

The OPA2227 is unity-gain stable and features high slew rate (2.3 V/μs) and wide bandwidth (8 MHz).

The OPA2227 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 OPA2227 operational amplifier is a pin-for-pin replacement for the industry standard OP-27 with substantial

improvements across the board. The dual and quad versions are available for space savings and perchannel

cost reduction.

The OPA2227 is available in an SOIC-8 package. Operation is specified from –55°C to 125°C.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of

Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of the Texas

Instruments standard warranty. Production processing does not

necessarily include testing of all parameters.
