Function
Master Clock Input Pin
An external TTL clock should be input on this pin.
Audio Serial Data Clock Pin
Audio Serial Data Input Pin
L/R Clock Pin
Power-Down Mode Pin
When at “L”, the AK4341 is in the power-down mode, held in reset and
AOUTL/R are held in VCOM. The AK4341 must be reset once upon
power-up.
Soft Mute Pin in parallel control mode
“H”: Enable, “L”: Disable
Auto Setting Mode Pin
“L”: Manual Setting Mode, “H”: Auto Setting Mode
Audio Data Interface Format Pin
“L”: 24bit MSB Justified, “H”: I2S
De-emphasis Enable Pin
“H”: Enable, “L”: Disable
Rch Analog Output Pin
When PDN pin = “L”, outputs VCOM voltage.
Lch Analog Output Pin
When PDN pin = “L”, outputs VCOM voltage.
Output Buffer Power Supply Pin
Normally connected to VSS with a 0.1
μ
F ceramic capacitor in parallel with a
10
μ
F electrolytic cap.
Ground Pin
DAC Power Supply Pin
DAC Common Voltage Pin
Normally connected to VSS with a 10
μ
F electrolytic cap.
Outputs VCOM VDD voltage either PDN pin = “L” or “H”.
Gain Control Pin.
“H”: +6dB, “L”: 0dB, open: +12dB.
When PDN=“H”, the Gain pin is connected to VDD and VSS with 50k
Ω
resisters and held to VDD/2 when open. When PDN=“L”, connected to VSS
with 50k
Ω
resister.
