DESCRIPTION (CONTINUED...)
The DAC088S085 is one of a family of pin compatible DACs, including the 10-bit DAC108S085 and the 12-bit
DAC128S085. All three parts are offered with the same pinout, allowing system designers to select a resolution
appropriate for their application without redesigning their printed circuit board. The DAC088S085 operates over
the extended industrial temperature range of −40°C to +125°C.
