Description

Description

The TDA8950 is a high efficiency class-D audio power amplifier. The typical output power is 2 × 150 W with a speaker load impedance of 4 Ω. The TDA8950 is available in the HSOP24 power package and DBS23P power package. The amplifier operates over a wide supply voltage range from ±12.5 V to ±40 V and consumes a low quiescent current.

Features

•  Pin compatible with TDA8920B for both HSOP24 and DBS23P packages
•  Symmetrical high operating supply voltage range from ±12.5 V to ±40 V
•  Stereo full differential inputs, usable as stereo Single-Ended (SE) or mono Bridge-Tied Load (BTL) amplifier
•  High output power at typical applications
•  Low noise in BTL due to BD-modulation
•  Smooth pop noise-free start-up and switch down
•  Zero dead time Pulse Width Modulation (PWM) output switching
•  Fixed frequency
•  Internal or external clock switching frequency
•  High efficiency
•  Low quiescent current
•  Advanced protection strategy: voltage protection and output current limiting
•  Thermal foldback
•  Fixed gain of 30 dB in SE and 36 dB in BTL
•  Full short-circuit proof across load
