The device features low noise, digital error correction, and an SOIC-8 package. The ultrastable output is 0.05% accurate with a temperature coefficient as low as 1.0 ppm/°C. 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. The VRE4100 is recommended for use as a reference for 14, 16, or 18 bit data converters which require a precision reference. The VRE4100 offers superior performance over standard on-chip refer...
