• Manufacturer Part Number: ak4673
• Description: Stereo Codec With Mic/hp-amp And Touch Screen Controller
• Manufacturer: AKM Semiconductor, Inc.

Parameter
Mono Input: MIN pin (AIN3 bit = “0”; External Input Resistance=20kΩ)
Maximum Input Voltage
Gain
Stereo Input: LIN2/RIN2/LIN4/RIN4 pins; LIN3/RIN3 pins (AIN3 bit = “1”)
Maximum Input Voltage
Gain
Full-differential Mono Input: IN4+/− pins (L4DIF bit = “1”)
Maximum Input Voltage
Gain
Note 18. Maximum voltage is in proportion to both AVDD and external input resistance (Rin). Vin = 0.6 x AVDD x Rin
Note 19. The gain is in inverse proportion to external input resistance.
Note 20. Maximum Input voltage is proportional to AVDD voltage. Vout = 0.6 x AVDD (typ).
Note 21. Maximum Input voltage is proportional to AVDD voltage. Vout = (IN4+) − (IN4−) = 1.2 x AVDD (typ). The
Note 22. Vout = (LOP) − (LON) at LODIF bit = “1”.
