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
