Texas Instruments LM4950
The LM4950 is a dual audio power amplifier primarily designed for demanding applications in flat panel monitors and TV's. It is capable of delivering 3.1 watts per channel to a 4Ω single-ended load with less than 1% THD+N or 7.5 watts mono BTL to an 8Ω load, with less than 10% THD+N from a 12VDC power supply. The LM4950 does not require bootstrap capacitors or snubber circuits.| Part No. | LM4950 |
