LM321

Low Power Single Op Amp

General Description

The LM321 brings performance and economy to low power

systems. With a high unity gain frequency and a guaranteed

0.4V/µs

slew

rate,

the

quiescent

current

is

only

430µA/amplifier (5V). The input common mode range in-

cludes ground and therefore the device is able to operate in

single supply applications as well as in dual supply applica-

tions. It is also capable of comfortably driving large capaci-

tive loads.

The LM321 is available in the SOT23-5 package. Overall the

LM321 is a low power, wide supply range performance op

amp that can be designed into a wide range of applications

at an economical price without sacrificing valuable board

space.
