1 / 50 page  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 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.
