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