Product specification

TDA1029

Fig.7 Circuit diagram showing input protection and indication.

Unused signal inputs

Any unused inputs must be connected to a d.c. (bias) voltage, which is within the d.c. input voltage range; e.g. unused

inputs can be connected directly to pin 10.

Circuits with standby operation

The control inputs (pins 11, 12 and 13) are high-ohmic at VSH ≤ 20 V (ISH ≤ 1 µA), as well as, when the supply voltage

(pin 14) is switched off.
