LMC6482 LMC6484 SNOS674I – OCTOBER 1997 – REVISED FEBRUARY 2024 LMC648x CMOS Rail-to-Rail Input and Output Operational Amplifiers 1 Features • Rail-to-rail input common-mode voltage range (specified over temperature) • Rail-to-rail output swing (within 20mV of supply rail, 100kΩ load) • Specified 3V, 5V, and 15V performance • Excellent CMRR and PSRR: 82dB • Ultra-low input current: 20fA • Specified for 2kΩ and 600Ω loads • Improved replacement for TLC272, TLC277 2 Applications • Data acquisition (DAQ) • Currency counter • Oscilloscope (DSO) • Intra-DC interconnect (METRO) • Macro remote radio unit (RRU) • Multiparameter patient monitor • Merchant telecom rectifiers • Train control and management • Process analytics (pH, gas, concentration, force, and humidity) • Three phase UPS 3 Description 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 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. Specified low-voltage characteristics and lowpower dissipation make the LMC648x a great choice for battery-operated systems. The LMC648x devices are available in PDIP, SOIC, and VSSOP packages.
