POWER DISSIPATION
AD9707 is dependent on several factors that include
The power supply voltages (AVDD, CLKVDD, and DVDD)
The full-scale current output, IOUTFS
The update rate, fCLOCK
The reconstructed digital input waveform
Power dissipation is directly proportional to the analog supply
current, IAVDD, and the digital supply current, IDVDD. IAVDD is equal to
to fCLOCK and increases with increasing analog output frequencies.
ratios (fOUT/fCLOCK) for various update rates with DVDD = 3.3 V.
ICLKVDD is directly proportional to fCLOCK and is higher for differential
clock operation than for single-ended operation, as shown in
Figure 84. This difference in clock current is due primarily to the
differential clock receiver, which is disabled in single-ended
clock mode.
