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

MDIF1 bit
■
The AK4648 has input selector for MIC-Amp. When MDIF1 and MDIF2 bits are “0”, INL1-0 and INR1-0 bits select
LIN1/LIN2/LIN3/LIN4 and RIN1/RIN2/RIN3/RIN4, respectively. When MDIF1 and MDIF2 bits are “1”, LIN1, RIN1,
LIN2 and RIN2 pins become IN1−, IN1+, IN2+ and IN2− pins respectively. In this case, full-differential input is
available (Figure 32).
