Function
DAC Current Output.
DAC Analog Ground. This pin should normally be tied to the analog ground of the system.
Digital Ground Pin.
Serial Clock Input. Data is clocked into the input shift register on each falling edge of the serial clock input.
This device can accommodate clock rates of up to 50 MHz.
Serial Data Input. Data is clocked into the 8-bit input register on each falling edge of the serial clock input.
Active Low Control Input. This is the frame synchronization signal for the input data. When SYNC goes low, it powers
on the SCLK and DIN buffers and the input shift register is enabled. Data is transferred on each falling edge of the
following 8 clocks.
Load DAC Input. Updates the DAC output. The DAC is updated when this signal goes low or alternatively; if this line is
held permanently low, an automatic update mode is selected whereby the DAC is updated after 8 SCLK falling edges
with SYNC low.
Positive Power Supply Input. This part can be operated from a supply of 2.5 V to 5.5 V.
DAC Reference Voltage Input Terminal.
DAC Feedback Resistor Pin. Establishes voltage output for the DAC by connecting to external amplifier output.
