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.

Features

(V_CC= 5V, T_A= 25˚C. Typical values unless specified).

n Gain-Bandwidth product

n Low supply current

n Low input bias current

n Wide supply voltage range

n Stable with high capacitive loads

n Single version of LM324

1MHz

430µA

45nA

+3V to +32V

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.

Applications

n Chargers

n Power supplies

n Industrial: controls, instruments

n Desktops

n Communications infrastructure
