LMC6484QML www.ti.com SNOSAS0A – OCTOBER 2010 – REVISED MARCH 2013 LMC6484QML CMOS Quad Rail-to-Rail Input and Output Operational Amplifier Check for Samples: LMC6484QML FEATURES 1 2 (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 5V and 15V Performance Operates at 3V. Excellent CMRR and PSRR: 82 dB Ultra Low Input Current: 20 fA High Voltage Gain (RL = 500 KΩ): 130 dB Specified for 2 KΩ and 600Ω Loads APPLICATIONS Data Acquisition Systems Transducer Amplifiers Hand-Held Analytic Instruments Medical Instrumentation Active Filter, Peak Detector, Sample and Hold, pH Meter, Current Source Improved Replacement for TLC274, TLC279 DESCRIPTION The LMC6484 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 LMC6484 is also an excellent upgrade for circuits using limited common-mode range amplifiers such as the TLC274 and TLC279. Maximum dynamic signal range is assured in low voltage and single supply systems by the LMC6484's rail-to-rail output swing. The LMC6484's rail-to-rail output swing is ensured for loads down to 600Ω. Ensured low voltage characteristics and low power diss...
