PIN/FUNCTION
No.
Pin Name
I/O
Function
Negative Charge Pump Capacitor Terminal Pin
Connect to CP with a 1.0
μ
F capacitor that should have the low ESR
(
Equivalent Series Resistance
) over all temperature range. When this
capacitor has the polarity, the positive polarity pin should be connected to the
CP pin. Non polarity capacitors can also be used.
Positive Charge Pump Capacitor Terminal Pin
Connect to CN with a 1.0
μ
F capacitor that should have the low ESR
(
Equivalent Series Resistance
) over all temperature range. When this
capacitor has the polarity, the positive polarity pin should be connected to the
CP pin. Non polarity capacitors can also be used.
Soft Mute Enable Pin (Internal pull down: 100k
)
“H”: Enable, “L”: Disable
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
Audio Data Interface Format Pin
“L”: Left Justified, “H”: I2S
Rch Analog Output Pin
When power down, outputs VSS(0V, typ).
Lch Analog Output Pin
When power down, outputs VSS(0V, typ).
