Micropower, Rail-to-Rail Input and Output CMOS
Operational Amplifier
General Description
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, guaranteed 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 ex-
cellent upgrade for circuits using limited common-mode range
amplifiers.
The LMC6464, with guaranteed specifications at 3V and 5V,
is especially well-suited for low voltage applications. A quies-
cent power consumption of 60 μW per amplifier (at V
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 sys-
tems.
