LMC6462 Dual/LMC6464 Quad
Micropower, Rail-to-Rail Input and Output CMOS
Operational Amplifier
General Description
The LMC6462/4 is a micropower version of the popular
LMC6482/4, combining Rail-to-Rail Input and Output Range
with very low power consumption.
The LMC6462/4 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 sigal range. This rail-to-rail performance
of the amplifier, combined with its high voltage gain makes it
unique among rail-to-rail amplifiers. The LMC6462/4 is an
excellent upgrade for circuits using limited common-mode
range amplifiers.
The LMC6462/4, with guaranteed specifications at 3V and
5V, is especially well-suited for low voltage applications. A
quiescent power consumption of 60 µW per amplifier (at V
= 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.
