描述 The LMC6482 device 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. 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 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 rail-to-rail output swing of the LMC6482. The rail-to-rail output swing is ensured for loads down to 600 Ω of the device. Ensured low-voltage characteristics and low-power dissipation make the LMC6482 especially well-suited for battery-operated systems. LMC6482 is also available in a 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.特性Typical Unless Otherwise Noted Rail-to-Rail Input Common-Mode Voltage Range (Ensured Over Temperature) Rail-to-Rail Output Swing (Within 20-mV of Supply Rail, 100-kΩ Load) Ensured 3-V, 5-V, and 15-V Performance Excellent CMRR and PSRR: 82 dB Ultralow Input Current: 20 fA High Voltage Gain (R L = 500 k Ω): 130 dB Specified for 2-kΩ and 600-Ω Loads Power-Good Output Available in VSSOP Package
