Product description
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.
Features
(Typical unless otherwise noted)
* Ultra Low Supply Current 20 uA/Amplifier

* Low Input Current 150 fA
* Low Input Offset Voltage 0.25mV
Applications
* Battery Operated Circuits
* Transducer Interface Circuits
* Portable Communication Devices
* Medical Applications
