DESCRIPTION
The DAC7615 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 zeroscale (000H), selectable via the RESETSEL pin. The individual DAC inputs are double buffered to allow
GND
for simultaneous update of all DAC outputs. The device can be powered from a single +5V supply or from dual +5V and 5V supplies. Low power and small size makes the DAC7615 ideal for automatic test equipment, DAC-per-pin programmers, data acquisition systems, and closed-loop servocontrol. The device is available in 16-pin plastic DIP, 16-lead SOIC, and 20-lead SSOP packages and is guaranteed over the 40°C to +85°C temperature range.

Exposure to absolute maximum conditions for extended periods may affect device reliability.
ELECTROSTATIC DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Burr-Brown recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
