The LMV321IDCKR is an operational amplifier, typically used in applications that require high input impedance, low output impedance, and high gain. It works by comparing the voltage between the non-inverting input (+) and inverting input (-) and driving the output to balance the inputs. Here's a summary of the key circuit principle:
Voltage Gain: The LMV321 is a single operational amplifier with a high open-loop gain, typically used for linear amplification. Power Supply: This op-amp operates on a dual supply (positive and negative), though it can also be used with a single supply in some configurations. Differential Input: The voltage difference between the two input pins (inverting and non-inverting) determines the output. Feedback Loop: In many applications, a resistor network is used to provide negative feedback from the output to the inverting input, stabilizing the gain and response of the op-amp.FAQ for LMV321IDCKR
