FEATURES  
DESCRIPTION  
Low voltage operation and low power dissipation  
make the LMC6574/2 ideal for battery-powered  
systems.  
2
(Typical Unless Otherwise Noted)  
Guaranteed 2.7V and 3V Performance  
Rail-to-Rail Output Swing (Within 5 mV of  
Supply Rail, 100 kΩ Load)  
3V amplifier performance is backed by 2.7V  
guarantees to ensure operation throughout battery  
lifetime. These guarantees also enable analog circuits  
to operate from the same 3.3V supply used for digital  
logic.  
Ultra-Low Supply Current: 40 μA/Amplifier  
Low Cost  
Ultra-Low Input Current: 20 fA  
Battery life is maximized because each amplifier  
dissipates only micro-watts of power.  
High Voltage Gain @ VS=2.7V,  
RL=100 kΩ: 120 dB  
Specified for 100 kΩ and 5 kΩ Loads  
The LMC6574/2 does not sacrifice functionality for  
low voltage 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.  
Available in VSSOP Package  
APPLICATIONS  
Transducer Amplifier  
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.  
Portable or Remote Equipment  
Battery-Operated Instruments  
Data Acquisition Systems  
Medical Instrumentation  
Improved Replacement for TLV2322 and  
TLV2324  
This device is built with Texas Instruments' advanced  
Double-Poly Silicon-Gate CMOS process.  
LMC6572 is also available in VSSOP package which  
is almost half the size of a SOIC-8 device.
