Dual Micropower, Rail-to-Rail Input and Output CMOS Operational Amplifier
The LMC6462 is a micropower version of the popular LMC6482, combining Rail-to-Rail Input and Output Range with very low power consumption. The LMC6462 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 25kOhm, 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 is an excellent upgrade for circuits using limited common-mode range amplifiers. The LMC6462, with guaranteed specifications at 3V and 5V, is especially well-suited for low voltage applications. A quiescent power consumption of 60uW per amplifier (at VS = 3V) can extend the useful life of battery operated systems. The amplifiers 150fA input current, low offset voltage of 0.25mV, and 85dB CMRR maintain accuracy in batterypowered systems.
