TDA4VEN-Q1: specific connectivity requirements and unused package balls

Furuna Yamamoto

Part Number: TDA4VEN-Q1

Tool/software:

"tda4ven-q1.pdf" Please tell me about chapter 5.4.

- Power supply pins.
For unused circuit power supplies, can the high-frequency capacitors be reduced from EVM (ex. 1/2 to 1/4)?

- Signal pins

Is there any problem with N.C. for signal terminals of unused circuits, except for the signals listed in Table 5-83?

1. All input power pins must be connected to a supply voltage within ROC levels. Unused circuit supplies can use reduced qty of decoupling capacitors.

2. Yes, unused circuit signal pins can be left as No Connects, except for signals listed otherwise in Table 5-83.
