General Description
The MAX9759 mono class D, audio power amplifier provides class AB amplifier audio performance with the benefits of class D efficiency, eliminating the need for a heatsink and extending battery life. The MAX9759 delivers up to 3.2W of continuous power into a 4Ω load while offering greater than 90% efficiency. Maxim’s next-generation, low-EMI modulation scheme allows the amplifier to operate without an external LC filter while still meeting FCC EMI-radiated emission levels.
