3 Description
The TAS6582-Q1 is a two-channel, digital-input, highvoltage,
Class-D audio amplifier that supports up
to 45-V supply voltage. In combination with up to
10-A output current, this device delivers maximum
output power and high fidelity audio in high and low
impedance loads. The device provides two channels
at 118 W (45 V, 8 Ω, 1% THD, BTL) and 215 W (45 V,
4 Ω, 1% THD, BTL).
The TAS6582-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 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 realtime
load diagnostics which operate independent from
host and audio input.
To optimize system efficiency, the integrated DSP of
the TAS6582-Q1 enables Class-H envelope tracking
control, eliminating the need for development of
complex tracking software and making local boost
voltage control possible without the need for an
external microcontroller.
The TAS6582-Q1 device features an additional lowlatency
signal path for each channel, providing up to
70% faster signal processing at 48 kHz which enables
time-sensitive Active Noise Cancellation (ANC), Road
Noise Cancellation (RNC) applications.
The device is offered in a 64-pin QFP package with
the exposed thermal pad up.
