Description

The TAS2770 is a mono digital input Class-D audio amplifier optimized for efficiently driving high peak
power into small loudspeakers. The Class-D amplifier is capable of delivering 18.3 W of peak power into a
4-

Ω

load while sustaining 1% THD+N at a battery voltage of 13.8 V. Integrated speaker voltage and

current sense provides for real time monitoring of loudspeaker behavior. Up to eight devices can share a
common bus via either I2S, TDM + I

C or Soundwire

SM

interfaces. Two PDM inputs are provided for low

latency playback or sensor aggregation.

The TAS2770EVM supports evaluation and development with the TAS2770 device through the following
interfaces:

USB interface

Software

The TAS2770 EVM is easily configured with PurePath Console 3 running the TAS2770 plug-in.

NOTE:

The evaluation driver currently distributed for use with this EVM will periodically inject a tone

into the data stream. This is intentional behavior for this version of the driver. We are in the
process of legal procurement of the full release version of this driver which will resolve this
issue. Once available, it will be provided to the end user.
