High Precision, Low Noise  
OPERATIONAL AMPLIFIERS  
FEATURES  
DESCRIPTION  
● LOW NOISE: 3nV/√Hz  
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.  
● WIDE BANDWIDTH:  
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 optimized 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 applications 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  
● TELECOM EQUIPMENT  
● GEOPHYSICAL ANALYSIS  
● VIBRATION ANALYSIS  
● SPECTRAL ANALYSIS  
● PROFESSIONAL AUDIO EQUIPMENT  
● ACTIVE FILTERS  
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 configura-  
tions. Operation is specified from –40°C to +85°C.
