The LMC6464 is a micropower version of the popular LMC6484, combining Rail-to-Rail Input and Output Range with very low power consumption.
The LMC6464 provides an input common-mode voltage range that exceeds both rails. The rail-to-rail output swing of the amplifier, ensured for loads down to 25 KΩ, assures maximum dynamic signal range. This rail-to-rail performance of the amplifier, combined with its high voltage gain makes it unique among rail-to-rail amplifiers. The LMC6464 is an excellent upgrade for circuits using limited common-mode range amplifiers.
The LMC6464, with ensured specifications at 3V and 5V, is especially well-suited for low voltage applications. A quiescent power consumption of 60 μW per amplifier (at VS = 3V) can extend the useful life of battery operated systems. The amplifier's 150 fA input current, low offset voltage of 0.25 mV, and 85 dB CMRR maintain accuracy in battery-powered systems.
