Infineon MA2304DNSXUMA1

The MA2304DNS is a 2x37 W audio amplifier with integrated audio DSP and I2S/TDM audio interface. It features the MERUS™ multilevel switching amplifier technology enabling unmatched power efficiency at both low and high output power. Multilevel switching also relaxes EMI and enables inductor‑less applications with lower cost and no compromise in audio performance or efficiency. A high order internal feedback loop ensures low THD for excellent audio performance. The integrated DSP offers a configurable processing flow and can be used to correct and tune real speaker applications with e.g. equalization, limiting and more.The ultra‑low idle power consumption is at least five times lower than the traditional class D audio amplifiers in the market, making MA2304DNS ideal for battery powered speaker applications with extended battery life and/or reduced battery cell cost. In mains‑powered multichannel applications, the reduced and scalable EMI performance, enables otherwise impossible industrial designs, without the necessity for a heatsink or a traditional LC filter.

Symbol Views

(not all views will be available for every part)

Normal: Standard and most popular representation of schematic symbol

ALT_1 (IEEE view): Symbol representation in a way that is more graphical in explaining what the purpose of each pin is. For connectors and most discretes (as we use these views) it is simply an alternate view for people to use depending on the situation. For instance connectors can be generally an input, an output or neither. Resistors can be vertical or horizontal.

ALT_2 (demorgan): Demorgan is a name for an equivalent Gate structure. so for instance an AND gate and an OR gate can be represented by its Demorgan equivalent of a NOR gate.

Sometimes a device is fractured into multiple symbols (often for high pin count parts). If that is the case, you can preview the different symbols that make up the device by selecting them in this drop down.

Footprint Views

(not all views will be available for every part)

Basic: Our standard footprint view showing, contact area, pin number, top, top assembly

Detailed: Additional info to help you evaluate the part and the footprint including: dimension, silkscreen, soldermask, and solderpaste

PinDetail: Highlights the pin to pad contact area dimensions

Displays min/typ/max pad sizes for footprint per IPC specification (not all sizes will be available for every part)
