Overview
The OPA4325IPWR is a quad-channel operational amplifier produced by Texas Instruments. It is part of the OPAx325 family, which includes precision, low-voltage complementary metal-oxide semiconductor (CMOS) operational amplifiers. This device is optimized for very low noise and wide bandwidth while operating on a low quiescent current. The OPA4325 is particularly suited for applications requiring high accuracy, low power consumption, and wide supply voltage range.
