FEATURES
DESCRIPTION
Low voltage operation and low power dissipation
make the LMC6574/2 ideal for battery-powered
systems.

•
(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

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.
