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
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.
