3 Description

The TAS6682-Q1 is a two-channel, digital-input, high-voltage, Class-D audio amplifier that supports up to 45V supply voltage. Combined with up to 13A output current, this device delivers maximum output power and high fidelity audio in high and low impedance loads. The device provides two channels at 118W (45V, 8Ω, 1% THD+N, BTL) and 218W (45V, 4Ω, 1% THD+N, BTL).

The TAS6682-Q1 integrates DC and AC load diagnostics to determine the status of the connected loads before enabling the output stage. During audio playback, the status can be monitored through the output current sense and temperature of each channel 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 using real-time load diagnostics which operate independently from the host and audio input.

To optimize system efficiency, the integrated DSP of the TAS6682-Q1 enables Class-H envelope tracking control, eliminating the need for complex tracking software and making local boost voltage control possible without an external microcontroller.

The TAS6682-Q1 device features an additional low-latency signal path for each channel, providing up to 70% faster signal processing at 48kHz and support an audio signal path latency of < 100us at 96kHz sample rate, which enables time-sensitive active noise cancellation (ANC), road noise cancellation (RNC) applications.

The TAS6682-Q1 is offered in a 64-pin QFP package with the exposed thermal pad up, pin-to-pin, and software compatible with TAS6684A-Q1.
