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 (220

µA/

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 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.

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.
