LMP2011 Single/ LMP2012 Dual/ LMP2014 Quad High Precision, Rail-to-Rail Output Operational
Amplifier
General Description
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 traditional amplifiers. The combination of the LMP201X characteristics 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 precision and long term stability.
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.

Note 1: Absolute Maximum Ratings indicate limits beyond which damage may occur. Operating Ratings indicate conditions for which the device is intended to be
functional, but specific performance is not guaranteed. For guaranteed specifications and test conditions, see the Electrical Characteristics.
Note 2: Typical values represent the most likely parametric norm.
Note 3: Limits are 100% production tested at 25˚C. Limits over the operating temperature range are guaranteed through correlations using statistical quality control
(SQC) method.
