Overview
LMC6462 Dual/LMC6464 Quad Micropower, Rail-to-Rail Input and Output CMOS Operational Amplifier May 1999 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 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.
