Digital Data Bit 13, (Most Significant Bit) through Digital Data Bit 0, (Least Significant Bit).
Control Pin for Power-Down mode. Sleep Mode is active high; Connect to ground for Normal Mode. Sleep
pin has internal 20µA active pulldown current.
Connect to analog ground to enable internal 1.2V reference or connect to AV
reference.
Reference voltage input if internal reference is disabled. Reference voltage output if internal reference is
enabled. Use 0.1µF cap to ground when internal reference is enabled.
Full Scale Current Adjust. Use a resistor to ground to adjust full scale output current. Full Scale Output
Current = 32 x V
For use in reducing bandwidth/noise. Recommended: connect 0.1µF to AV
The complimentary current output of the device. Full scale output current is achieved when all input bits
are set to binary 0.
Current output of the device. Full scale output current is achieved when all input bits are set to binary 1.
Connect 0.1µF capacitor to ACOM.
Analog Supply (+3V to +5V).
Connect to Analog Ground.
Connect to Digital Ground.
Digital Supply (+3V to +5V).
Clock Input. Input data to the DAC passes through the “master” latches when the clock is low and is
latched into the “master” latches when the clock is high. Data presented to the “slave” latch passes
through when the clock is logic high and is latched into the “slave” latches when the clock is logic low.
Adequate setup time must be allowed for the MSBs to pass through the thermometer decoder before the
clock goes high. This master-slave arrangement comprises an edge-triggered flip-flop, with the DAC
being updated on the rising clock edge. It is recommended that the clock edge be skewed such that setup
time is larger than the hold time.
