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 VDD, any variations may alter parameters accordingly.
5. When the IRQ Output is at VDD.
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.
