Product Summary

The TDA8950 is a high efficiency class-D audio power ampliﬁer. The TDA8950 is 2×150 W with a speaker load impedance of 4Ω. The TDA8950 is available in the HSOP24 power package and DBS23P power package. The TDA8950 operates over a wide supply voltage range from ±12.5 V to ±40 V and consumes a low quiescent current. Applications of the TDA8950 include: DVD, Mini and micro receiver, Home Theater In A Box (HTIAB) system and High power speaker system.

Parametrics

TDA8950J absolute maximum ratings: (1) supply voltage VP: 90V ( non-operating mode; VDD-VSS) ; (2) repetitive peak output current IORM: 9.2A; (3) storage temperature Tstg: -55 to +155°C; (4) ambient temperature Tamb: -40 to +155°C; (5) junction temperature, Tj: 150°C; (6) voltage on pin MODE VMODE: 0 to 6V (referenced to SGND) ; (7) voltage on pin OSC: 0 to OSC; (8) input voltage VI: -5V to +5V (referenced to SGND; pin IN1P; IN1M; IN2P and IN2M) ; (8) voltage on pin PROT VPROT: 0 to 12V; (9) electrostatic discharge voltage Vesd: -1800 to +1800V; (10) total quiescent current: 75mA (Operating mode; no load; no RC-snubber network connected) .

Features

TDA8950J features: (1) Pin compatible with TDA8920B for both HSOP24 and DBS23P packages; (2) ymmetrical high operating supply voltage range from ±12.5V to ±40V; (3) Stereo full differential inputs, usable as stereo Single-Ended (SE) or mono Bridge-Tied Load (BTL) amplifier; (4) Low noise in BTL due to BD-modulation; (5) Smooth pop noise-free start-up and switch down; (6) Zero dead time Pulse Width Modulation (PWM) output switching; (7) Fixed frequency; (8) Internal or external clock switching frequency; (9) High efficiencyLow quiescent current Advanced protection strategy: voltage protection and output current limiting; (10) Thermal foldback; (11) Fixed gain of 30 dB in SE and 36 dB in BTL; (12) Full short-circuit proof across load.
