Summary
To help the user investigate and evaluate the TAS5270M performance and capabilities, a fully populated evaluation board has been created. This board is shown in Figure 1-1. Connected to a PC, an external power supply (4.5V ≤ PVDD ≤ 26.4V) and a signal source, the TAS5270M Evaluation Board easily exercises the amplifier’s features.
The TAS5720M device is a high-efficiency mono Class-D audio power amplifier optimized for high transient power capability to use the dynamic power headroom of small loudspeakers. It is capable of delivering more than 15-W continuously into a 4-Ω speaker. The device has two address pins, which allow up to 8 I2C addressable devices to share a common TDM bus.
The TAS5720M device SAIF supports a variety of standard stereo serial audio formats including I2S, Left
Justified and Right Justified. It also supports a time division multiplexed (TDM) format that is capable of transporting up to 8 channels of audio data on a single bus.
