LMC2001 High Precision, 6MHz Rail-To-Rail Output Operational Amplifier

August 1999

LMC2001

High Precision, 6MHz Rail-To-Rail Output Operational

Amplifier

General Description

The LMC2001 is a new precision amplifier that offers un-

precedented accuracy and stability at an affordable price

and is offered in miniature (SOT23-5) package. This device

utilizes patented techniques to measure and continually cor-

rect the input offset error voltage. The result is an amplifier

which is ultra stable over time, and temperature. It has excel-

lent CMRR and PSRR ratings, and does not exhibit the fa-

miliar 1/f voltage and current noise increase that plagues tra-

ditional amplifiers. The combination of the LMC2001

characteristics makes it a good choice for transducer ampli-

fiers, high gain configurations, ADC buffer amplifiers, DAC

I-V conversion, and any other 5V application requiring preci-

sion and/or stability.

Other useful benefits of the LMC2001 are rail-to-rail output,

low supply current of 750碌A(chǔ), and wide gain-bandwidth

product of 6MHz. The LMC2001 comes in 5 pin SOT23 and

8 pin SOIC. These extremely versatile features found in the

LMC2001 provide high performance and ease of use.
