• Manufacturer Part Number: AK7782
• Description: Dual Audio DSP with 24bit 5ch ADC & SRC
• Manufacturer: AKM [Asahi Kasei Microsystems]

(VSS1=VSS2=VSS3=0V;
Note 4. All voltages with respect to ground.
Note 5. VSS1, VSS2 and VSS3 must be connected to the same ground plane.
WARNING: Operation at or beyond these limits may result in permanent damage to the device.
(VSS1=VSS2=VSS3=0V;
Note 4. All voltages with respect to ground.
Note 6. The VREFH pin is normally connected to AVDD.
Note 7. The VREFL pin is normally connected to VSS1.
Note 8. The analog input voltage is proportional to the (VREFH-VREFL) voltage.
Note 9. The power-up sequence between AVDD, DVDD and DVDD18 is not critical. The INITRSTN pin should be held
Note 10. Do not turn off the power supply of the AK7782 when the power supplies of the surrounding device are turned
MS1337-E-00-PB
WARNING: AKM assumes no responsibility for the usage beyond the conditions in the datasheet.
