... D0 – Bits CLK Description The SPT5240 is a 10-bit digital-to-analog converter that performs at an update rate of 400M words per second. The architecture achieves excellent high-frequency performance with very low power dissipation. This makes it ideal for all types of battery-operated equipment requiring high-speed digital-to-analog conversion ...

... DGND 7 AGND 8 Theory of Operation The SPT5240 is a 10-bit 400 MWPS digital-to-analog converter. It integrates a DAC core with a bandgap reference and operates from a +3.3V power supply. The DAC architecture is a compound differential current output DAC consisting of a 6-bit fully segmented DAC for the MSBs and a 4-bit fully segmented DAC for the LSBs. ...

... Outputs (IO and IO P +A3.3V Power Supplies and Grounding The SPT5240 may be operated in the range of 3.0 to 3.6 volts. Normal operation is recommended to be separate analog and digital supplies operating at +3.3 volts. All power supply pins should be bypassed as close to the package as possible with the smallest capacitor closest to the device ...
