CMOS Dual Rail-to-Rail Input and Output Operational Amplifier - LMC6482

LMC6482 (ACTIVE)

CMOS Dual Rail-to-Rail Input and Output Operational Amplifier

Recommended alternative parts

  • LMC6462  -  Less Power
  • LMP7702  -  Higher Precision, RRIO,lower Power Consumption, Higher CMRR

Description

The LMC6482 provides 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 it unique among rail-to-rail input amplifiers.

It is ideal for systems, such as data acquisition, that require a large input signal range. The LMC6482 is also an excellent upgrade for circuits using limited common-mode range amplifiers such as the TLC272 and TLC277.

Maximum dynamic signal range is assured in low voltage and single supply systems by the LMC6482's rail-to-rail output swing. The LMC6482's rail-to-rail output swing is ensured for loads down to 600Ω.

Ensured low voltage characteristics and low power dissipation make the LMC6482 especially well-suited for battery-operated systems.

LMC6482 is also available in VSSOP package which is almost half the size of a SOIC-8 device.

See the LMC6484 data sheet for a Quad CMOS operational amplifier with these same features.
