Level and Threshold Setting 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 В± 0.4% offering a 25 ppm/В°C temperature coefficient and 5 mA of external load driving capability.
The DAC8426 contains four 8-bit voltage-output CMOS D/A
converters on a single chip. A 10 V output bandgap reference
sets the output full-scale voltage. The circuit also includes four …
