LMC6572/LMC6574 Dual and Quad Low Voltage (2.7V and 3V) Operational Amplifier
August 2000
LMC6572/LMC6574 Dual and 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.

Note 1:
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
intended to be functional, but specific performance is not guaranteed. For guaranteed specifications and test conditions, see the Electrical Characteristics.
Note 2:
Human body model, 1.5 kΩ in series with 100 pF.
Note 3:
Applies to both single-supply and split-supply operation. Continuous short circuit operation at elevated ambient temperature can result in exceeding the
maximum allowed junction temperature of 150˚C.
Note 4:
The maximum power dissipation is a function of T
