Notes
1. TDA7073A: VP = 5 V; RL = 8 Ω; The typical voltage swing = 5.8 V and Vloss is 2.1 V therefore IO = 0.36 A and
Ptot = 2 × 0.76 W = 1.52 W; Tamb (max) = 150 − 1.52 × 50 = 74 °C.
2. TDA7073AT: VP = 5 V; RL = 16 Ω; typical voltage swing = 5.8 V and Vloss is 2.1 V therefore IO = 0.18 A and
Ptot = 2 × 0.38 W = 0.76 W; Tamb (max) = 150 − 0.76 × 95 = 77 °C.
