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 750µA, 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.
