LMV321 Typical Application Diagram
The LMV321 is a cost-effective alternative for applications that require low power consumption and small footprints. Specification tables are provided for operation with 2.7 V and 5 V power supplies. This family of amplifiers is suited for portable, battery-operated devices because of the increased signal-to-noise performance and ultra-low quiescent current. Because the device's common-mode input range covers the ground, it can be used to test low-side current shunts. The ultra-small packages allow for proximity to the signal source on the PCB, which reduces noise pickup.
Weigh scales, comparators, adders, and subtractors are all possible applications for this IC. The LMV321 circuit is as follow:
LMV321Circuit
The non-inverting configuration of the LMV321 Op-amp is used. The op-gain amps are set to ten. We used a 1K resistor and a 9.1K resistor for, as you can see for the simulation we used a variable potentiometer, by varying the potentiometer we can change the input voltage and the output voltage will also change, to power the op-amp we used +12V and -12V supply, as the gain of the op-amp is 10 so if we provide 1V at the input we will get 10V at the output, as the simulated circuit
