PIN TYPE DESCRIPTION
NAME DGS (VSSOP) DQF (WSON)
AGND 4 3 Ground Ground reference point for all circuitry on the device.
NC 3 — — No connection. Leave floating.
NC 9 — — No connection. Leave floating.
SCLK/SCL 6 5 Input Serial interface clock. SPI or I2C mode.
SDIN/SDA 8 7 Input/output SPI mode: Serial interface data input. Data are clocked into the input shift register on each falling edge of the SCLK pin.
I2C mode: Data are clocked into or out of the input register. This pin is a bidirectional, SDA drain data line that must be connected to the supply voltage with an external pullup resistor.
SPI2C 5 4 Input Interface select pin.
Digital interface in SPI mode if SPI2C = 0
Digital interface in I2C mode if SPI2C = 1
SPI2C pin must be kept static after device powers up.
SYNC/A0 7 6 Input SPI mode: Active low serial data enable. This input is the frame synchronization signal for the serial data. When the signal goes low, the serial interface input shift register is enabled.
I2C mode: Four-state address input 0.
VDD 1 1 Power Analog supply voltage (2.7 V to 5.5 V)
VOUT 2 2 Output Analog output voltage from the DAC
VREFIO 10 8 Input/output When using the internal reference, this pin is the reference output voltage pin (default). Reference input to the device when operating with external reference.
