1 / 13 page  LMC6572 Dual/LMC6574 Quad Low Voltage (2.7V and 3V) Operational Amplifier General Description Low voltage operation and low power dissipation make the LMC6574/2 ideal for battery-powered systems. 3V amplifier performance is backed by 2.7V guarantees to ensure operation throughout battery lifetime. These guaran- tees also enable analog circuits to operate from the same 3.3V supply used for digital logic. Battery life is maximized because each amplifier dissipates only micro-watts of power. The LMC6574/2 does not sacrifice functionality for low volt- age operation. The LMC6574/2 generates 120 dB of open-loop gain just like a conventional amplifier, but the LMC6574/2 can do this from a 2.7V supply. These amplifiers are designed with features that optimize low voltage operation. The output voltage swings rail-to-rail to maximize signal-to-noise ratio and dynamic signal range. The common-mode input voltage range extends from 800 mV below the positive supply to 100 mV below ground. This device is built with National’s advanced Double-Poly Silicon-Gate CMOS process. LMC6572 is also available in MSOP package which is al- most half the size of a SO-8 device.
