FEATURES - 2 (Typical Unless Otherwise Noted) - Ultra Low Supply Current 20 μA/Amplifier - Ensured Characteristics at 3V and 5V - Rail-to-Rail Input mon-Mode Voltage Range - Rail-to-Rail Output Swing - (within 10 m V of rail, VS = 5V and RL = 25 kΩ) - Low Input Current 150 f A - Low Input Offset Voltage 0.25 m V APPLICATIONS - Battery Operated Circuits - Transducer Interface Circuits - Portable munication Devices - Medical Applications - Battery Monitoring DESCRIPTION The LMC6462/4 is a micropower version of the popular LMC6482/4, bining Rail-to-Rail Input and Output Range with very low power consumption. The LMC6462/4 provides an input mon-mode voltage range that exceeds both rails. The rail-to-rail output swing of the amplifier, ensured for loads down to 25 kΩ, assures maximum dynamic signal range. This rail-to-rail performance of the amplifier, bined with its high voltage gain makes it unique among rail-to-rail amplifiers. The LMC6462/4 is an excellent upgrade for circuits using limited monmode range amplifiers. The LMC6462/4, with ensured 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 f A input current, low offset voltage of 0.25 m V, and 85 d B CMRR maintain accuracy in battery-powered systems.
