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.  
Features  
(Typical unless otherwise noted)  
n Guaranteed 2.7V and 3V Performance  
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.  
n Rail-to-Rail Output Swing (within 5 mV of supply rail,  
100 kload)  
n Ultra-Low Supply Current: 40 µA/Amplifier  
n Low Cost  
Battery life is maximized because each amplifier dissipates  
only micro-watts of power.  
n Ultra-Low Input Current: 20 fA

@
n High Voltage Gain VS 2.7V, RL 100 k: 120 dB  
n Specified for 100 kand 5 kloads  
n Available in MSOP Package  
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.  
Applications  
n Transducer Amplifier  
n Portable or Remote Equipment  
n Battery-Operated Instruments  
n Data Acquisition Systems  
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.  
n Medical Instrumentation  
n Improved Replacement for TLV2322 and TLV2324  
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.
