SBOS110A – MAY 1998 – REVISED JANUARY 2005  
High Precision, Low Noise  
OPERATIONAL AMPLIFIERS  
FEATURES  
ꢀ LOW NOISE: 3nV/√Hz  
DESCRIPTION  
The OPA227 and OPA228 series op amps combine low  
ꢀ WIDE BANDWIDTH:  
noise and wide bandwidth with high precision to make them  
the ideal choice for applications requiring both ac and preci-  
sion dc performance.  
OPA227: 8MHz, 2.3V/µs  
OPA228: 33MHz, 10V/µs  
ꢀ SETTLING TIME: 5µs  
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.  
(significant improvement over OP-27)  
ꢀ HIGH CMRR: 138dB  
ꢀ HIGH OPEN-LOOP GAIN: 160dB  
ꢀ LOW INPUT BIAS CURRENT: 10nA max  
ꢀ LOW OFFSET VOLTAGE: 75µV max  
ꢀ WIDE SUPPLY RANGE: ±2.5V to ±18V  
ꢀ OPA227 REPLACES OP-27, LT1007, MAX427  
ꢀ OPA228 REPLACES OP-37, LT1037, MAX437  
ꢀ SINGLE, DUAL, AND QUAD VERSIONS  
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.  
APPLICATIONS  
ꢀ DATA ACQUISITION  
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.
