• Manufacturer Part Number: ak4648
• Description: Stereo Codec With Mic/hp/spk-amp
• Manufacturer: AKM Semiconductor, Inc.

Parameter
Stereo Input: LIN2/RIN2/LIN4/RIN4 pins; LIN3/RIN3 pins (AIN3 bit = “1”)
Maximum Input Voltage (Note 30)
Gain
Full-differential Mono Input: IN4+/− pins (L4DIF bit = “1”)
Maximum Input Voltage (Note 31)
Gain
Note 30. Maximum input voltage is proportional to AVDD voltage. Vin = 0.6 x AVDD (typ.).
Note 31. Maximum input voltage is proportional to AVDD voltage. Vin = (IN4+) − (IN4−) = 1.2 x AVDD (typ.).
Note 32. Vout = (LOP) − (LON) at LODIF bit = “1”.
Note 33. Signals with same amplitude and phase are input to LIN and RIN at SPKMN bit = “0”. When the input signal is

The signals with same amplitude and inverted phase should be input to IN4+ and IN4− pins, respectively.
LIN or RIN, these values subtract 6.02dB from the above value.
