3 Description

The LM321 brings performance and economy to low

power systems. With a high unity gain frequency and

a specified 0.4-V/μs slew rate, the quiescent current

is only 430-μA/amplifier (5 V). The input common

mode range includes ground and therefore the device

is able to operate in single supply applications as well

as in dual supply applications. It is also capable of comfortably driving large capacitive loads.

The LM321 is available in the SOT-23 package. Overall the LM321 is a low power, wide supply range

performance operational amplifier that can be

designed into a wide range of applications at an

economical price without sacrificing valuable board

space.
