DESCRIPTION
The LM321 brings performance and economy to low
power systems. With a high unity gain frequency and
a specified 0.4V/µs slew rate, the quiescent current is
only 430µA/amplifier (5V). 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 op amp that can be designed into a
wide range of applications at an economical price
without sacrificing valuable board space.
