Description for the LMC6464
The LMC6462 and LMC6464 (LMC646x) are micropower versions of the popular LMC6482 and LMC6484, combining a rail-to-rail input and output range with very low power consumption.
The LMC646x provide an input common-mode voltage range that exceeds both rails. The rail-to-rail output swing of the amplifiers, specified for loads down to 25kΩ, provides maximum dynamic signal range. This rail-to-rail performance of the amplifiers, combined with a high voltage gain, makes these device unique among rail-to-rail amplifiers. The LMC646x are an excellent upgrade for circuits using limited common-mode range amplifiers.
The LMC646x, with specifications at 3V and 5V, is an excellent choice for low-voltage applications. A quiescent power consumption of 60µW per amplifier (at VS = 3V) can extend the useful life of battery-operated systems. The 150fA input current, low offset voltage of 0.25mV, and 85dB CMRR maintain accuracy in battery-powered systems.
