3 Description

The TAS2320 is a mono, digital input Class-D audio

amplifier designed for efficiently driving high peak

power into loudspeakers.

Device is optimized to deliver best battery life

for real-use cases of music playback and voice

calls. Advanced efficiency optimization features like

Y-bridge, and algorithms enable the device to produce

best-in-class efficiency across all power regions

of operation. The Class-D amplifier is capable of

delivering 15W output power using external PVDD

supply.

Up to four devices can share a common bus via

I2S/TDM + I2C interfaces. The device also supports

five HW Control pins that can configure the device for

the desired mode of operation.
