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.
