Ultra-low Bias Current, Precision CMOS Rail-to-Rail Input and Output Dual Operational Amplifier

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. The LMC648x are also an excellent upgrade

for circuits using limited common-mode 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.

Specified low-voltage characteristics and low-power dissipation make the LMC648x a great choice for battery-operated

systems.

The LMC648x devices are available in PDIP, SOIC, and VSSOP

packages.
