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 single-channel 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.
