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 kΩ load)

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 V_S2.7V, R_L100 kΩ: 120 dB

n Specified for 100 kΩ and 5 kΩ loads

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.
