NOTES
1Current reflects device operating with no output loads.
2V
IN = 0.4 V and 2.4 V.
3Idle refers to ADSP-2104/ADSP-2109 state of operation during execution of IDLE instruction. Deasserted pins are driven to either V
DD or GND.
For typical supply current (internal power dissipation) figures, see Figure 7.
Figure 7. ADSP-2104/ADSP-2109 Power (Typical) vs. Frequency
1 POWER REFLECTS DEVICE OPERATING WITH NO OUTPUT LOADS.
2 IDLE REFERS TO ADSP-2104/ADSP-2109 OPERATION DURING EXECUTION OF IDLE INSTRUCTION.
DEASSERTED PINS ARE DRIVEN TO EITHER VDD OR GND.
3 MAXIMUM POWER DISSIPATION AT VDD = 5.5V DURING EXECUTION OF IDLE n INSTRUCTION.
