LM4140 High Precision Low Noise Low Dropout Voltage Reference July 2000 LM4140 High Precision Low Noise Low Dropout Voltage Reference General Description 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 during the final production testing.
