10-bit quad DAC with I²C bus
The DS3911T+: The I²C data interface integrates directly with a 2-wire bus, so four independent analog outputs can be set from a single microcontroller port without dedicating GPIOs — useful for trimming bias voltages, setting comparator thresholds, or generating analog control signals in a mixed-signal system.
Supply rails and temperature range
The -40°C to 100°C operating temperature covers industrial and extended-commercial environments — the part can sit in an outdoor telecom cabinet or an unvented enclosure without exceeding the junction limit.
Housed in a 14-lead TDFN with an exposed pad — the 3x5 mm footprint with the thermal paddle underneath needs a via array to the ground plane to pull heat out of the die. The surface-mount package is pick-and-place ready. The external reference input means the output full-scale voltage is set by the reference voltage applied — choose a precision reference that matches the ADC reference in the same system to keep the transfer function ratiometric.
