DESCRIPTION

The VRE4100 is a low cost, high precision bandgap reference that operates from +5V. 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.
