DESCRIPTION

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

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 –40

°C to +85°C
