Description
General part information
TAS2770 Series
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
