02 20000314 -

Product specification; second version; supersedes initial version TDA8942P-01 of

14 April 1999 (9397 750 04879). Modifications:

• Table 1 on page 1:THD: Max value 0.1% changed to → 0.3%;

SVRR: Typ value 65 dB → added

• Ordering options removed

• Figure 1 on page 2: Block diagram; pin numbers changed OUT2− → 7 and OUT2+ → 10

• Figure 2 on page 3: Pin configuration; pin numbers changed OUT2− → 7 and OUT2+ → 10

• Table 3 on page 3: Pin description; pin numbers changed OUT2− → 7 and OUT2+ → 10

• Section 8 “Functional description”:

– Section 8.1 “Input configuration” on page 4 → added.

– Section 8.2 “Power amplifier” on page 5: ........, capable of delivering a peak output

current of 1.5 A → changed to 2 A.

– Section 8.2.1 “Output power measurement” on page 5 → added

– Section 8.2.2 “Headroom” on page 5 → added

• Section 8.3 “Mode selection”:

– Standby mode: VMODE > (VCC − 0.5 V) → changed to (VCC − 0.5 V) < VMODE < VCC; The

power consumption of the TDA8942P will be reduced to <0.18 mW → added.

– Mute mode: the DC level of the input and output pins remain on half the supply

voltage → added;

– 2.5 V < VMODE < (VCC − 1.5 V) → changed to 3 V < VMODE < (VCC − 1.5 V)

– Section 8.3.1 “Switch-on and switch-off” on page 6 → added.

• Section 8.5 “Built-in protection circuits” on page 6 → added

• Table 5 on page 7:

– Ptot value added 2.2 W

– VCC(sc) value added 12 V

• Table 6 on page 7: Rth(j-a) value 55 K/W changed to → 57 K/W

• Table 7 on page 7: VMODE - mute mode - value Min 2.5 → changed to 3 V

• Table 8 on page 8:

– THD: Max value 0.1% changed to → 0.3%

– SVRR; Typ values 65 and 60 dB → added

– αcs; Typ value 75 dB → added

– Rsource changed to → RS in table and associated table notes; Value added RS = 0 Ω;

– Table note [2]: .... 100 mV (RMS).... changed to → ... 700 mV (RMS)....

• Figure 3 to 13: figures added

• Section 13 “Internal circuitry” on page 13: → added

• Figure 14: figure modified
