The LM321 brings performance and economy to low power systems. With a high unity gain frequency and a guaranteed 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 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.
