The TAS6754-Q1 is a four-channel digital-input Class-D audio amplifier that implements 1L modulation only requiring one inductor per BTL channel reducing system size and cost by removing four inductors compared to a traditional design. Additionally, 1L modulation lowers switching losses compared to traditional Class-D modulation schemes.
The TAS6754-Q1 integrates DC and AC Load Diagnostics to determine the status of the connected loads. During audio playback this status can be monitored through output current sense which is available for each channel and reports the measurement to a host processor through TDM with minimal delay. The device monitors the output load condition while playing audio through real-time load diagnostics independent of the host and audio input.
The TAS6754-Q1 device features an additional low latency signal path for each channel, providing up to 70% faster signal processing at 48kHz which enables time-sensitive Active Noise Cancellation (ANC), Road Noise Cancellation (RNC) applications.
The device supports global temperature, channel temperature and PVDD values via I2C readout for easy system level thermal management.
The device is offered in a 56 pin HSSOP package with the exposed thermal pad up.
