Texas Instruments LMC6482
The LMC6482 and LMC6484 (LMC648x) devices provide a common-mode range that extends to both supply rails. This rail-to-rail performance combined with excellent accuracy, due to a high CMRR, makes these devices unique among rail-to-rail input amplifiers. The devices are an excellent choice for systems that require a large input signal range, such as data acquisition.| Part No. | LMC6482 |

DESCRIPTION
The LMC648x are also an excellent upgrade for circuits using limited commonmode range amplifiers, such as the TLC272, TLC274, TLC277 and TLC279. Maximum dynamic signal range is provided in low voltage and single supply systems by the rail-to-rail output swing of the LMC648x. The rail-to-rail output swing is maintained for loads down to 600Ω of the device.
