The LM4140 series of precision references are designed to combine high
accuracy, low drift and noise with low power dissipation in a small
package.
The LM4140 is the industry's first reference with output voltage options
lower than the bandgap voltage.
The key to the advance performance of the LM4140 is the use of
EEPROM registers and CMOS DACs for temperature coefficient curvature
correction and trimming of the output voltage accuracy of the device
