TDA8954TH Pinout Diagram

● High output power in typical applications:

● SE 2 × 210 W, RL = 4 Ω (VDD = 41 V; VSS = –41 V)

● SE 2 × 235 W, RL = 3 Ω (VDD = 39 V; VSS = –39 V)

● SE 2 × 150 W, RL = 6 Ω (VDD = 41 V; VSS = –41 V)

● BTL 1 × 420 W, RL = 8 Ω (VDD = 41 V; VSS = –41 V)

● Symmetrical operating supply voltage range from ±12.5 V to ±42.5 V

● Stereo full differential inputs, can be used as stereo SE or mono BTL amplifier

● Low noise

● Smooth pop noise–free start-up and switch off

● 2-pin diagnostics for protection circuits

● Fixed frequency internal or external clock

● High efficiency (≈93 %

● Zero dead time switching

● Low quiescent current

● Advanced protection strategy: voltage protection and output current limiting

● Thermal FoldBack (TFB) with disable functionality

● Fixed gain of 30 dB in SE and 36 dB in BTL applications

● Fully short–circuit proof across load

● BD modulation in BTL configuration

● Clock protection
