LMC6572 Dual/LMC6574 Quad Low Voltage (2.7V and 3V) Operational Amplifier
December 1996
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鈥檚 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.
