3 Description

The TAS6511-Q1 is a mono-channel, digital-input,

Class-D audio amplifier that supports 2 MHz switching

frequency enabling a cost and size-optimized singlechannel

solution. The device operates from 4.5 V to

18 V and delivers up to 30 W (14.4 V, 4 Ω, 10

THD+N) and up to 50 W (14.4 V, 2 Ω, 10 THD+N).

The device integrates DC and AC load diagnostics

to determine the status of the connected load before

enabling the output stage. Additionally, the device can

monitor the output load condition while in PLAY mode

with or without audio using real-time load diagnostics

which operates independently from the host and audio

input.

TAS6511-Q1 can monitor the output current, PVDD

voltage, and temperature of the device and

can report this data through TDM or I2S. The

integrated DSP of the TAS6511-Q1 enables advanced

protection features such as PVDD foldback, thermal

foldback, and Speaker Guard? Pro power limiter.

The DSP also enables an additional low-latency

signal path, providing up to 70 faster signal

processing at 48 kHz for time-sensitive Active Noise

Cancellation (ANC) and Road Noise Cancellation

(RNC) applications.

The device is available in a small pad-down TSSOP

package.
