Notes
1. Does not include current drawn by any attached DRAM.
2. Serial Clock, Command Data, CS, A1/DEI and A2/DCK inputs.
3. CAS, WE and A0 to A9 outputs.
4. All measurements are made at 5.0 volts V , any variations may alter parameters accordingly.
DD
5. When the IRQ Output is at V_DD.
6. The optimum range of levels for a good Signal-to-Noise Ratio.
7. Audio frequency responses will vary with respect to Xtal/clock frequency.
8. Reply Data output.
9. IRQ output.
10. RAS Outputs.
11. Passband is reduced to (typically) 2700Hz when a sample rate of 25kb/s or 50kb/s is employed.
12. Measured with a -20dB input level to avoid codec slope-overload.
13. For optimum noise performance this input should be driven from a source impedance of less than 100Ω.
