Description
DAC Feedback Resistor. Establish voltage output for the DAC by connecting to external
amplifier output.
DAC Reference Voltage Input.
Positive Power Supply Input. These parts can operate from a supply of 2.5 V to 5.5 V.
Active Low Control Input. This is the frame synchronization signal for the input data. Data is
loaded to the shift register upon the active edge of the following clocks.
Serial Data Input. Data is clocked into the 16-bit input register upon the active edge of the serial
clock input. By default, in power-up mode data is clocked into the shift register upon the falling
edge of SCLK. The control bits allow the user to change the active edge to a rising edge.
Serial Clock Input. By default, data is clocked into the input shift register upon the falling edge
of the serial clock input. Alternatively, by means of the serial control bits, the device can be
configured such that data is clocked into the shift register upon the rising edge of SCLK.
Ground Pin.
DAC Current Output.
Exposed pad must be connected to ground.
