OPA2237UA
DESCRIPTION
The OPA237 op amp family is one of Texas Instruments?
MicroAmplifier? series of miniature products. In addition
to small size, these devices feature low offset voltage, low
quiescent current, low bias current, and a wide supply
range. Single, dual, and quad versions have identical
specifications for maximum design flexibility. They are
ideal for single-supply, battery-operated, and
space-limited applications, such as PCMCIA cards and
other portable instruments.
OPA2277UA
The OPAx277 series precision operational amplifiers OPA4277
replace the industry standard OP-177. They offer PDIP (14) 6.35 mm ? 19.30 mm
improved noise, wider output voltage swing, and are (1) For all available packages, see the orderable addendum at
twice as fast with half the quiescent current. Features the end of the data sheet.
include ultralow offset voltage and drift, low bias
current, high common-mode rejection, and high 0.1 Hz to 10 Hz Noise

versions have identical specifications, for maximum
design flexibility

? Low Bias Current: 1-nA maximum (?20 ?V maximum) is so low, user adjustment is
usually not required. However, the single version ? Wide Supply Range: ?2 V to ?18 V

OPA4131PA
The OPA131 series of FET-input op amps provides high
performance at low cost. Single, dual, and quad versions in
industry-standard pinouts allow cost-effective design options.
The OPA131 series offers excellent general-purpose performance, including low offset voltage, drift, and good dynamic
characteristics.
Single, dual, and quad versions are available in DIP and SO
packages. Performance grades include commercial and industrial temperature ranges.

OPA4340UA
The OPA340 series rail-to-rail CMOS operational
amplifiers are optimized for low-voltage, single-supply
operation. Rail-to-rail input and output and highspeed operation make them ideal for driving sampling
analog-to-digital (A/D) converters. They are also wellsuited for general purpose and audio applications as
well as providing I/V conversion at the output of
digital-to-analog (D/A) converters. Single, dual, and
quad versions have identical specifications for design
flexibility.
The OPA340 series operate on a single supply as low
as 2.5 V with an input common-mode voltage range
that extends 500 mV below ground and 500 mV
above the positive supply. Output voltage swing is to
within 1 mV of the supply rails with a 100-k? load.
These devices offer excellent dynamic response
(BW = 5.5 MHz, SR = 6 V/?s), yet quiescent current
is only 750 A. Dual and quad designs feature
completely independent circuitry for lowest crosstalk
and freedom from interaction
