LC75411ES, 75411WS
Function
30
• Equalizer F1 band filter configuration capacitor
29
connection pins.
28
Connect capacitor between
7
LF1C1 (RF1C1) and LF1C2 (RF1C2)
8
LF1C2 (RF1C2) and LF1C3 (RF1C3)
9
• Equalizer F3 band circuit filter configuration
27
capacitor connection pins.
10
Connect high-pass compensation capacitor
between LF3C1 (RF3C1) and VSS.
26
• Equalizer output pins
11
24
• Fader block input pins
13
• Drive at low impedance.
23
• Fader output pins. Attenuation is possible separately
22
for the front end and rear end. The attenuation
14
amount is the same for L and R.
15
• Connect a capacitor of a few tens of µF between
43
Vref and VSS as a 0.55 VDD voltage generator,
current ripple countermeasure.
