• Manufacturer Part Number: ak4647vq
• Description: Stereo Codec With Mic/hp-amp
• Manufacturer: AKM Semiconductor, Inc.

ASAHI KASEI
Parameter
Mono Input: MIN pin (External Input Resistance=20k )
Maximum Input Voltage (Note 17)
Gain Note 18(Note 18)
Power Supplies:
Power Up (PDN pin = “H”)
Power Down (PDN pin = “L”) (Note 21)
Note 17. Maximum voltage is in proportion to both AVDD and external input resistance (Rin). Vin = 0.6 x AVDD x Rin
Note 18. The gain is in inverse proportion to external input resistance.
Note 19. PLL Master Mode (MCKI=12.288MHz) and PMADL = PMADR = PMDAC = PMLO = PMHPL = PMHPR =
Note 20. PMADL = PMADR = PMDAC = PMLO = PMHPL = PMHPR = PMVCM = PMPLL = PMBP bits = “1” and
Note 21. All digital input pins are fixed to DVDD or DVSS.
