FET-INPUT OPERATIONAL AMPLIFIERS
™
MicroAmplifier Series
FEATURES
● FET INPUT: IB = 5pA
● LOW OFFSET VOLTAGE: 1.5mV
● WIDE SUPPLY RANGE: ±2.25V to ±18V
● LOW QUIESCENT CURRENT: 220µA/channel
● EXCELLENT SPEED/POWER: 1MHz
● INPUT TO POSITIVE SUPPLY
DESCRIPTION
OPA137 series FET-input operational amplifiers are designed
for low cost and miniature applications. In addition to small
size (SOT-23-5 and MSOP-8 packages), they provide low
input bias current (5pA), low quiescent currrent (220µA/
channel), and high open-loop gain (94dB).
Either single (+4.5V to +36V) or dual (±2.25 to ±18V)
supplies can be used. The input common-mode voltage range
includes the positive supply—suitable for many single-supply
applications. Single, dual, and quad versions have identical
specifications for maximum design flexibility.
● MicroSIZE PACKAGES: SOT-23-5, MSOP-8
● SINGLE, DUAL, AND QUAD
OPA137 op amps are easy to use and free from phase
inversion and overload problems found in some FET-input
amplifiers. High performance, including linearity, is main-
tained as the amplifiers swing to their specified limits. In
addition, the combination of high slew rate (3.5V/µs) and
wide bandwidth (1MHz) provide fast settling time assuring
good dynamic response. Dual and quad designs feature com-
pletely independent circuitry for lowest crosstalk and freedom
from interaction.
APPLICATIONS
● STRAIN GAGE AMPLIFIER
● PHOTODETECTOR AMPLIFIER
● PRECISION INTEGRATOR
● BATTERY-POWERED INSTRUMENTS
● TEST EQUIPMENT
The single (OPA137) packages are the tiny 5-lead SOT-23-5
surface mount, SO-8 surface mount, and 8-pin DIP. The dual
(OPA2137) comes in the miniature MSOP-8 surface mount,
SO-8 surface mount, and 8-pin DIP packages. The quad
(OPA4137) packages are the SO-14 surface mount and the
14-pin DIP. All are specified from –40°C to +85°C and operate
from –55°C to +125°C. A SPICE macromodel is available for
design analysis.
