Operating from 2.7V to 5.5V supply with only 210uA typical supply current per amplifier, it is optimized for battery-powered and low-voltage applications. The device provides 1.1MHz gain-bandwidth, 1.4V\/us slew rate, and rail-to-rail output swing that maximizes dynamic range in single-supply designs. The input common-mode range includes ground, allowing direct sensing of ground-referenced signals. The LMV324 is a low-voltage version of the industry-standard LM324, providing a drop-in upgrade for 3V and 5V systems.","working_principle":"The LMV324IDT uses a CMOS input stage with rail-to-rail output stage for low-voltage operation. (1) Input Stage: A P-channel MOSFET differential pair provides the input common-mode range from ground to VCC-0.9V. The input bias current is typically 5nA. (2) Gain Stage: A folded-cascode gain stage provides the open-loop voltage gain of approximately 80dB. Internal compensation ensures stability at unity gain. (3) Output Stage: A CMOS push-pull output stage swings from rail to rail (within millivolts of the supply rails at light loads), maximizing output dynamic range in single-supply applications. (4) Bias Circuit: An internal bias network provides stable operating point over the 2.7V to 5.5V supply range with only 210uA per amplifier.","pin_description":"
