DESCRIPTION
The UTC LM321’s quiescent current is only 430µA (5V). The
UTC LM321 brings performance and economy to low power
systems, With a high unity gain frequency and a specified 0.4V/µs
slew rate. 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.
