OPA227/OPA2227/OPA4227 pdf dat

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 precision dc performance.
The OPA227 is unity gain stable and features high
slew rate (2.3V/ms) and wide bandwidth (8MHz). The
OPA228 is optimized for closed-loop gains of 5 or
greater, and offers higher speed with a slew rate of
10V/ms 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 applications requiring high precision.
The OPA227 and OPA228 series op amps are pinfor-
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.
