3 Description
The TAS6684-Q1 is a four-channel, digital-input, highvoltage,
Class-D audio amplifier that supports up
to 45V supply voltage. When 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 four channels
at 118W (45V, 8Ω, 1% THD, BTL) and 215W (45V,
4Ω, 1% THD, BTL).
The TAS6684-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 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 TAS6684-Q1 enables Class-H envelope tracking
control, eliminating the need for the development of
complex tracking software and making local boost
voltage control possible without the need for an
external microcontroller.
The TAS6684-Q1 device features an additional lowlatency
signal path for each channel, providing up to
70% faster signal processing at 48kHz and support
latency < 100us of audio signal path at 96kHz
sample rate, which enables time-sensitive Active
Noise Cancellation (ANC), Road Noise Cancellation
(RNC) applications.
The TAS6684-Q1 is offered in a 64-pin QFP package
with the exposed thermal pad up, which package is
pin-to-pin compatible with TAS6584-Q1.
