APPLICATION INFORMATION

Preliminary specification

TDA4566

(1) Residual carrier reduced to 20 mV peak-to-peak (R = 1 kΩ, C = 100 pF).

(2) Switching sequence for delay times shown in Table 1.

(3) R14−18 = 1.2 kΩ for TDA4566.

R14−18 = 1.15 kΩ for TDA4566A (27 kΩ resistor connected in parallel to 1.2 kΩ).
