1 Operating temperature range is as follows: B Version: −40°C to +85°C.
2 100% production tested.
3 fMCLK = 6.25 MHz, Frequency Word = 5671C71C HEX, fOUT = 2.11 MHz.
4 Measured with the digital inputs static and equal to 0 V or DVDD. The AD9835 is tested with a capacitive load of 50 pF. The part can be operated with higher capacitive
loads, but the magnitude of the analog output will be attenuated. See Figure 7.
