TAS5722LEVM: 15W @ 4Ω, Class D, 4.5 ~ 17V in

Summary

To help investigate and evaluate the TAS5722L performance and capabilities, a fully populated evaluation board has been created.

Connected to a PC, an external power supply (4.5V ≤ PVDD ≤ 17V), and a signal source, the TAS5722L Evaluation Board easily exercises the features of the amplifier.

The TAS5722L device is a high-efficiency mono Class-D audio power amplifier which includes integrated digital output clipper, several gain options, and a wide power supply operating range. It operates with a nominal supply voltage from 4.5 V to 17 VDC.

TAS5722L is optimized for high transient power capability to utilize the dynamic power headroom of small loudspeakers. It is capable of delivering more than 15 W of continuous power into a 4-Ω speaker.

The digital time division multiplexed (TDM) interface enables up to 8 devices to share the same bus.
