DEScription

The VRE4112/VRE4125/VRE4141 are low cost, high precision bandgap references that operate from +5 V. These devices feature low noise, digital error correction, and an SOIC-8 package. The ultra stable output is 0.05 accurate with a temperature coefficient as low as 1.0 ppm/ºC. The improvement in overall accuracy is made possible by using EEPROM registers and CMOS DAC’s for temperature and initial error correction. The DAC trimming is done after assembly which eliminates assembly related shifts.

Applications

This series is recommended for use as a reference for 14, 16, or 18-bit data converters which require a precision reference. The series offers superior performance over standard on-chip references commonly found with data converters.
