• Manufacturer Part Number: AK5388EQ
• Description: 120dB 24-bit 192kHz 4-Channel ADC
• Manufacturer: AKM [Asahi Kasei Microsystems]

■
When the MONO pin is set to “H”, the AK5388 is in Mono mode. In this mode, dynamic range and S/N can be improved
by approximately 3dB when the same analog signal is inputted to LIN1 and RIN1, LIN2 and RIN2. The LIN1 and RIN1
data are summed and the amplitude is attenuated into half to be output from the SDTO1 pin. The LIN2 and RIN2 data are
summed and the amplitude is attenuated into half to be output from the SDTO2 pin.
