Low voltage operation and low power dissipation make the LMC6574/2 ideal for
3V amplifier performance is backed by 2.7V guarantees to ensure operation throughout
battery lifetime. These guarantees 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
The LMC6574/2 does not sacrifice functionality for low voltage 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
This device is built with Texas Instruments' advanced Double-Poly Silicon-Gate CMOS
LMC6572 is also available in VSSOP package which is almost half the size of a SOIC-8
