Overview
The LMC6482AIMX/NAK2, produced by Texas Instruments, is a CMOS dual rail-to-rail input and output operational amplifier. This device is notable 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 systems. The LMC6482 offers excellent accuracy due to its high Common Mode Rejection Ratio (CMRR) and low input offset voltage, making it a superior choice for upgrading circuits that use limited common-mode range amplifiers like the TLC272 and TLC277. The device is available in various packages, including PDIP, SOIC, and VSSOP, and is suitable for low-voltage and single supply systems due to its rail-to-rail output swing and low power dissipation.
