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.
