The TAS2770 is a mono, digital input Class-D audio amplifier optimized for efficiently driving small loudspeakers . The output power, protection features and packages make TAS2770 a good choice for Smart speakers, Bluetooth speakers, home automation devices, Notebook computers and tablets.

The Class-D amplifier is capable of delivering 20W of continuous power into a 4-Ω load at 16V and 15W into an 8-Ω load at 16V both at 1% THD. The broad voltage input range of 4.5-16V and the high output power makes this amplifier versatile enough to work with battery power or with line powered systems

A Brown-Out preventer tracks peak voltage and automatically self-limits the gain to the voltage available. This hardware implemented feature reduces the amplifier’s demand on system power preventing both audio cut out and system shutdown

The TAS2770 can be used as a conventional amp or with host based speaker protection algorithms. The integrated speaker voltage and current sense provides for real time feedback of loudspeaker conditions to the protection algorithms through a return I2S path.

Up to eight devices can share a common bus via either I 2S/TDM + I 2C.

The TAS2770 device is available in a 26-pin, 0.4-mm pitch QFN for a compact PCB footprint.
