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.

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is in-
tended 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 TJ(Max), θJA, and TA. The maximum allowable power dissipation at any ambient temperature is
PD = (TJ(Max) − TA)/θJA. All numbers apply for packages soldered directly into a PC board.
Note 5: Typical values represent the most likely parametric norm.
Note 6: All limits are guaranteed by testing or statistical analysis.
Note 7: V+ = 3V, VCM = 1.5V and RL connected to 1.5V. For Sourcing tests, 1.5V ≤ VO ≤ 2.5V. For Sinking tests, 0.5V ≤ VO ≤ 1.5V.
Note 8: Connected as Voltage Follower with 1.0V step input. Number specified is the slower of the positive and negative slew rates.
Note 9: Input referred, V+ = 3V and RL = 100 kΩ connected to 1.5V. Each amp excited in turn with 1 KHz to produce VO = 2 VPP.
