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.

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 main­tained 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 com­pletely independent circuitry for lowest crosstalk and freedom
from interaction.

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.

ELECTROSTATIC
DISCHARGE SENSITIVITY

This integrated circuit can be damaged by ESD. Burr-Brown
recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling
and installation procedures can cause damage.

ESD damage can range from subtle performance degrada­tion to complete device failure. Precision integrated circuits
may be more susceptible to damage because very small
parametric changes could cause the device not to meet its
published specifications.
