Low-power Consumption Single Operation Amplifier

Function description

LMV321 is a low-power consumption system with good performance and economy. It has high unit gain frequency and the designated conversion rate of 0.4V/μs, and the quiescent current is only 430 μA / amplifier (5V). The input common-mode scope includes grounding; for this reason, the device can work in both single power supply applications and dual power supply applications. In addition, the device can drive large capacitive loads comfortably.

SOT-23 package is adopted for LMV321. Generally speaking, LMV321 is an operational amplifier with low power consumption and wide power supply ranges, which can be designed for various applications with favorable price.
