Key Differentiators
- True 16-bit resolution with ±1 LSB INL (vs DAC70508ZYZFT (14-bit))
- Integrated 2.5-V reference with 5 ppm/°C drift (vs AD5686RBRUZ (requires external reference))
- Ultra-small 16-DSBGA package (2.0 mm × 2.0 mm) (vs LTC2668IUH (32-QFN))
Design Notes
Decouple the AVDD and DVDD pins with 0.1-µF and 1-µF capacitors placed as close to the device as possible. Use a low-impedance ground plane to minimize noise. The internal reference output (VREF) should be bypassed with a 1-µF capacitor to ground to ensure stability.
For the DSBGA package, ensure the PCB layout matches the 16-ball footprint with proper solder mask and stencil design. Use via-in-pad or micro-vias to route signals from the small package. Keep SPI traces short and matched in length to avoid signal integrity issues.
Avoid exceeding the absolute maximum ratings for supply voltage and digital inputs. Ensure the SPI lines are not driven above DVDD. When using the internal reference, do not load it with more than 1 mA to maintain accuracy. Also, note that the power-on reset clears all registers to zero-scale, so initialize the device before use.
