TDA1579

TDA1579T

APPLICATION INFORMATION (Fig.1)

Notes

1. Sequence for measuring switch-on delay times (tdon)

a) Nominal BK or DK input signal at pin 13: Vi(p-p) = 8 mV; f = 57 kHz; modulation-on.

b) Pin 4 of the BK detector (pin 16 of the DK detector) is switched to ground to cause a low signal at the SK output

at pin 3 (DK output at pin 2).

c) tdon commences when the ground connection is removed from pin 4 (pin 16) as the positive-going VoBK signal at

pin 5 (VoDK signal at pin 15) crosses zero.

tdon ends when the positive-going edge of the SK output arrives at pin 13 (DK at pin 2).

2. Sequence for measuring switch-off delay times (tdoff)

a) Nominal operating conditions as in note 1.

b) tdoff commences when the input is switched off as the negative-going VoBK signal at pin 5 (VoDK signal at pin 15)

crosses zero.

tdoff ends when the negative-going edge of the SK output arrives at pin 3 (DK at pin 2).
