    Operational amplifiers are perhaps the most versatile, important, and widely used components in analog electronic circuits. The construction of analog electronic circuits cannot be imagined without operational amplifiers. An operational amplifier is essentially differential voltage amplifying device. When used with different combinations of capacitors, resistors, transistors, and other electronic devices, there are literally hundreds of op-amp based circuits which can be formed. Operational amplifiers are extensively used in signal conditioning, filtering, buffering, referencing, instrumentation, and analog-to-digital conversion applications. The great advantage of op-amps is that they can be used in negative feedback configuration which makes them very useful for signal processing and control system applications.

    What is LMV324IDR?

    The LMV324IDR is a quad low-voltage operational amplifier IC with rail to rail output swing developed by Texas Instruments. These operational amplifiers are ideal for applications which are space constrained, cost sensitive and low voltage operation. The LMV324IDR has performance specifications which exceed LM324. These ICs also feature ESD protection and low power shutdown mode. These general purpose operational amplifiers can be used in a wide range of applications.
