DESCRIPTION
Audio/PWM Processing
The TAS5717/TAS5719 is a 10-W/15-W, efficient,
digital
audio-power
amplifier
for
driving
stereo
– Independent Channel Volume Controls With
bridge-tied speakers. One serial data input allows
24-dB to Mute
processing of up to two discrete audio channels and
– Programmable Two-Band Dynamic Range
seamless integration to most digital audio processors
Control
and MPEG decoders. The device accepts a wide
– 14 Programmable Biquads for Speaker EQ
range
of
input
data
and
data
rates.
A
fully
programmable data path routes these channels to the
– Programmable Coefficients for DRC Filters
internal speaker drivers.
– DC Blocking Filters
The TAS5717/9 is a slave-only device receiving all
– 0.125-dB Fine Volume Support
clocks from external sources. The TAS5717/TAS5719
General Features
operates with a PWM carrier between a 384-kHz
– Serial Control Interface Operational Without
switching
rate
and
a
352-KHz
switching
rate,
MCLK
depending on the input sample rate. Oversampling
combined with a fourth-order noise shaper provides a
– Factory-Trimmed Internal Oscillator for
flat noise floor and excellent dynamic range from
Automatic Rate Detection
20 Hz to 20 kHz.
– Surface Mount, 48-Pin, 7-mm × 7-mm
HTQFP Package
– AD, BD, and Ternary PWM-Mode Support
– Thermal and Short-Circuit Protection
