NOTES
1Current reflects device operating with no output loads.
2VIN = 0.4 V and 2.4 V.
3Idle refers to ADSP-21xx state of operation during execution of IDLE instruction. Deasserted pins are driven to either V DD or GND.
4ADSP-2105 is not available in a 25 MHz speed grade.
For typical supply current (internal power dissipation) figures, see Figure 11.
