The DAC7614 is a quad, serial input, 12-bit, voltage output digital-to-analog converter (DAC) with guaranteed 12-bit monotonic performance over the ?40°C to +85°C temperature range. An asynchronous reset clears all registers to either mid-scale (800H) or zero-scale (000H), selectable via the RESETSEL pin. The device can be powered from a single +5V supply or from dual +5V and ?5V supplies.
Low power and small size makes the DAC7614 ideal for process control, data acquisition systems, and closed-loop servo-control. The device is available in 16-pin plastic DIP, 16-lead SOIC, or 20-lead SSOP packages, and is guaranteed over the ?40°C to +85°C temperature range.
