High Precision, Rail-to-Rail Output Operational Amplifier

General Description

Features

The LMP201X is a new precision amplifier family that offers

unprecedented accuracy and stability at an affordable price

and is offered in miniature packages. This device utilizes

patented techniques to measure and continually correct the

input offset error voltage. The result is an amplifier which is

ultra stable over time and temperature. It has excellent

CMRR and PSRR ratings, and does not exhibit the familiar

1/f voltage and current noise increase that plagues tradi-

tional amplifiers. The combination of the LMP201X charac-

teristics makes it a good choice for transducer amplifiers,

high gain configurations, ADC buffer amplifiers, DAC I-V

conversion, and any other 2.7V-5V application requiring pre-

cision and long term stability.

(For V_S= 5V, Typical unless otherwise noted)

n Low guaranteed V_OSover temperature

n Low noise with no 1/f

n High CMRR

n High PSRR

n High A_VOL

n Wide gain-bandwidth product

n High slew rate

n Low supply current

n Rail-to-rail output

n No external capacitors required

Other useful benefits of the LMP201X are rail-to-rail output,

a low supply current of 930 µA, and wide gain-bandwidth

product of 3 MHz. These extremely versatile features found

in the LMP201X provide high performance and ease of use.

Applications

n Precision instrumentation amplifiers

n Thermocouple amplifiers

n Strain gauge bridge amplifier
