The DAC63202W is a dual-channel buffered, force-sense output, voltage-output and current-output smart DAC that includes an NVM and internal reference, and available in a tiny 1.72-mm × 1.72-mm (nominal) package.

• In voltage-output mode, short the OUTx and FBx pins for each channel. In current-output mode, leave the FBx pins unconnected. The FBx pins function as inputs in comparator mode.
• The external reference must not exceed VDD, either during transient or steady-state conditions. For the best Hi-Z output performance, use a pullup resistor on the VREF pin to VDD. In case the VDD remains floating during the off condition, place a 100-kΩ resistor to AGND for proper detection of the VDD off condition.
• All the digital outputs are open drain; use external pullup resistors on these pins.
• The interface protocol is detected at power-on, and the device locks to the protocol as long as VDD is on.
• When allocating nonoverlapping I²C addresses on a system I²C bus, consider the broadcast address as well. I²C timeout can be enabled for robustness.
• SPI mode is 3-wire by default. Configure the GPIO pin as SDO in the NVM for SPI readback capability. The SPI clock speed in readback mode is slower than that in write mode.
• Power-down mode sets the DAC outputs in Hi-Z by default. Change the configuration appropriately for different power-down settings. The DAC channels can also power-up with a programmed DAC code in the NVM.
