Dual Low Voltage (2.7V to 3V) Operational Amplifier
LMC6572/LMC6574 Dual and Quad
Low Voltage (2.7V and 3V) Operational Amplifier
General DescriptionLow voltage operation and low power dissipation make the
LMC6574/2 idealfor battery-powered systems. amplifier performanceis backedby 2.7V guaranteesto
ensure operation throughout battery lifetime. These guaran-
tees also enable analog circuitsto operate from the same
3.3V supply usedfor digital logic.
Batterylifeis maximized because each amplifier dissipates
only micro-wattsof power.
The LMC6574/2 does not sacrifice functionalityfor low volt-
age operation. The LMC6574/2 generates 120dBof open-
loop gain just likea conventional amplifier, but the
LMC6574/2 cando this froma 2.7V supply.
These amplifiers are designed with features that optimize
low voltage operation. The output voltage swings rail-to-rail maximize signal-to-noise ratio and dynamic signal range.
The common-mode input voltage range extends from
800 mV below the positive supplyto 100 mV below ground.
This deviceis built with National’s advanced Double-Poly
Silicon-Gate CMOS process.
LMC6572is also availablein MSOP package whichisal-
most half the sizeofa SO-8 device.
