• Manufacturer Part Number: ak4644
• Description: Stereo Codec With Mic/hp/rcv-amp
• Manufacturer: AKM Semiconductor, Inc.

ASAHI KASEI
Parameter
Stereo Input: LIN2/RIN2 pins; LIN3/RIN3 pins (AIN3 bit = “1”)
Maximum Input Voltage (Note 20)
Gain
Power Supplies:
Power-Up (PDN pin = “H”)
Power-Down (PDN pin = “L”) (Note 23)
Note 20. Output voltage is proportional to AVDD voltage. Vout = 0.6 x AVDD (typ).
Note 21. PLL Master Mode (MCKI=12.288MHz) and PMADL = PMADR = PMDAC = PMLO = PMHPL = PMHPR =
Note 22. PMADL = PMADR = PMDAC = PMLO = PMHPL = PMHPR = PMVCM = PMPLL = PMMIN bits = “1”.
Note 23. All digital input pins are fixed to DVDD or DVSS.
Condtions: Ta=25°C; AVDD=DVDD=HVDD=3.3V; AVSS=DVSS=HVSS=0V; fs=44.1kHz, External Slave Mode,
