Texas Instruments offers the LMC6482 ultra-low bias current, precision CMOS rail-to-rail input and output operational amplifier

     Texas Instruments' LMC6482 device offers a common model circumference that extends to two power rails. This rail-to-rail performance, combined with excellent accuracy, makes it unique among rail-to-rail input amplifiers due to its high common-mode rejection ratio (CMRR). The device is ideal for systems, such as data acquisition, that require a large input signal range. The LMC6482 is also an excellent upgrade for circuits that use limited common model amps such as TLC272 and TLC277.

     The LMC6482's rail-to-rail output swing ensures maximum dynamic signal range in low-voltage and single-power systems. Rail-to-rail output swing ensures the load drops to 600 ohm for the device. Ensuring the low voltage characteristics and low power consumption makes the LMC6482 particularly suitable for battery driven systems. The LMC6482 is also available in the VSSOP package and is almost half the size of the SOIC-8 device. See LMC6484 datasheet for four CMOS operational amplifiers with these same features.
