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
