VP2

Fig.31 Application 1; supply voltage range 8 V < VP ≤ 18 V; 1-pin and 2-pin operation.

(1) Load conditions: quad SE (4 x 4

Ω), or dual BTL (2 x 8 Ω), or dual SE (2 x 4 Ω) and one BTL (1 x 8 Ω).

(2) RC combination not required in BTL mode.

(3) R1 and R2 values depend on Vswitching applied; the value of R1 and R2 connected in parallel should be minimum 10 kΩ.
