Ordering Information
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
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.
