  1. How to Easily Achieve Superior Audio Performance with Plug and Play Digital Input Class D Amplifiers
    Analog Dialogue

    Matt Felder

    This article introduces a family of plug-and-play class D amplifiers that simplify system design by eliminating the usual need for I2C programming, low-jitter sample clocks, logic level shifters, careful board design, or EMI filtering. It will explain how to These parts deliver high performance audio withwhile saving on space minimal area, cost, and effort.

      During my recent use, I noticed that the TxAMP CAL REF CODE contains 8 bits, ranging from 0 to 255. However, the diagram in datasheet only shows values from 0 to 100. Is it because there is no change after 100, so it was not included? Additionally, I would like …
