TDA8950
General description
The TDA8950 is a high efficiency class-D audio power amplifier. The typical output power is 2 x 150 W with a speaker load impedance of 4 Ohm.
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:
- SE 2 x 150 W, RL = 4 Ohm (VP = +-37 V)
- SE 2 x 170 W, RL = 4 Ohm (VP = +-39 V)
- SE 2 x 100 W, RL = 6 Ohm (VP = +-37 V)
- BTL 1 x 300 W, RL = 8 Ohm (VP = +-37 V)
- 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
