Overview
The LMC6482AIMX/S7002212, produced by Texas Instruments, is an ultra-low bias current, precision CMOS rail-to-rail input and output dual operational amplifier. This device is part of the LMC648x series, known for its extensive common-mode range that extends to both supply rails, making it ideal for systems requiring a large input signal range, such as data acquisition and battery-operated systems.
The LMC6482 offers excellent accuracy due to its high common-mode rejection ratio (CMRR) and power supply rejection ratio (PSRR), making it a superior choice for various applications where precision and reliability are crucial.
