DESCRIPTION The DAC7631 is a serial input, 16-bit, voltage out- put Digital-to-Analog Converter (D/A) with guaran- teed 15-bit monotonic performance over the –40°C to +85°C temperature range. An asynchronous reset clears all registers to either mid-scale (8000H) or zero-scale (0000H), selectable via the RESETSEL pin. The de- vice can be powered from a single +5V supply or from dual +5V and –5V supplies.
