PRODUCTION DATA
Refer to the PDF data sheet for device specific package drawings
The DACx3004 are programmed through either a 3-wire SPI or 2-wire I2C interface. A 4-wire SPI mode is enabled by mapping the GPIO pin as SDO. The SPI readback operates at a lower SCLK than the standard SPI write operation. The type of interface is determined based on the first protocol to communicate after device power up. After the interface type is determined, the device ignores any change in the type while the device is on. The interface type can be changed after a power cycle.
