2• Audio Input/Output • Benefits
– 20-W Into an 8-Ω Load From an 18-V Supply – Up to 90% Efficient
– Wide PVDD Range, From 8 V to 26 V – AD and BD Filter Mode Support
– Efficient Cl*-D Operation Eliminates – SNR: 106 dB, A-Weighted
Need for Heatsinks – EQ: Speaker Equalization Improves Audio
– One Serial Audio Input (Two Audio Performance
Channels) – DRC: Dynamic Range Compression. Can
– 2.1 Mode (2 SE + 1 BTL) Be Used As Power Limiter. Enables
– 2.0 Mode (2 BTL) Speaker Protection, Easy Listening,
– Single-Filter PBTL Mode Support Night-Mode Listening.
– I2C Address Selection Pin (Chip Select) – Separate DRC for Satellite and
Subchannels
– Supports 8-kHz to 48-kHz Sample Rate
(LJ/RJ/I2S) – Autobank Switching: Preload Coefficients
for Different Sample Rates. No Need to
• Audio/PWM Processing Write new Coefficients to the Part When
– Independent Channel Volume Controls With Sample Rate Changes.
24-dB to Mute – Autodetect: Automatically Detects
– Separate Dynamic Range Control for Sample-Rate Changes. No Need for
Satellite and Subchannels External Microprocessor Intervention
– 21 Programmable Biquads for Speaker EQ • Requires Only 3.3 V and PVDD
and Other Audio Processing Features
– Programmable Coefficients for DRC Filters APPLICATIONS
– DC Blocking Filters • Television
– Support for 3D Effects • iPod™ Dock
• General Features • Sound Bar
– Serial Control Interface Operational Without D*CRIPTION MCLK
– Factory-Trimmed Internal Oscillator for The TAS5711 is a 20-W, efficient, di*al audio power
Automatic Rate Detection amplifier for driving stereo bridge-tied speakers. One
serial data input allows processing of up to two
– Surface Mount, 48-Pin, 7-mm × 7-mm discrete audio channels and seamless integration to
HTQFP Package most di*al audio processors and MPEG decoders.
– Thermal and Short-Circuit Protection The device accepts a wide range of input data and
– Support for AD or BD Mode data rates. A fully programmable data path routes
these channels to the internal speaker drivers.
The TAS5711 is an I2S slave-only device receiving all
clocks from external sources. The TAS5711 operates
with a PWM carrier between 384-kHz switching rate
and 352-KHz switching rate depending on the input
sample rate. Oversampling combined with a
fourth-order noise shaper provides a flat noise floor
and excellent dynamic range from 20 Hz to 20 kHz
