GENERAL DESCRIPTION
The DAC8426 is a complete quad voltage output D/A converter with internal reference. This product fits directly into any existing 7226 socket where the user currently has a 10 V external reference. The external reference is no longer necessary. The internal reference of the DAC8426 is laser-trimmed to ±0.4% offering a 25 ppm/°C temperature coefficient and 5 mA of external load driving capability.
