The TAS6884-Q1 is a four-channel, digital-input, high-voltage, Class-D audio amplifier that supports up to 48V supply voltage. The device provides four channels at 155W (48V, 8Ω, 1% THD, BTL) and 250W (48V, 4Ω, 1% THD, BTL).
The TAS6884-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 TAS6884-Q1 enables Class-H envelope tracking control, eliminating the need for the development of complex tracking software and external microcontroller.
The TAS6884-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 < 100µs at 96kHz sample rate, which enables time-sensitive Active Noise Cancellation (ANC), Road Noise Cancellation (RNC) applications.
The TAS6884-Q1 is offered in a 64-pin QFP package with the exposed thermal pad up, TAS6884-Q1 is pin-to-pin compatible with TAS6684A-Q1.
