PRODUCTION DATA. TAS5727 SLOS670A – NOVEMBER 2010 – REVISED MAY 2016 TAS5727 25-W Digital Audio Power Amplifier With EQ and DRC 1 1 Features 1 • Audio Input and Output – 25 W Into an 8- Ω Load From a 20-V Supply – Wide PVDD Range, From 8 V to 26 V – Supports BTL Configuration With 4- Ω Load – Efficient Class-D Operation Eliminates Need for Heatsinks – One Serial Audio Input (Two Audio Channels) – I2C Address Selection Pin (Chip Select) – Single Output Filter PBTL Support – Supports 44.1-kHz to 48-kHz Sample Rate (LJ/RJ/I2S) • Audio and PWM Processing – Independent Channel Volume Controls With Gain of 24 dB to Mute With 0.125-dB Resolution Steps – Programmable Two-Band Dynamic-Range Control – 18 Programmable Biquads for Speaker EQ and Other Audio-Processing Features – Programmable Coefficients for DRC Filters – DC Blocking Filters • General Features – I2C Serial Control Interface Operational Without MCLK – Requires Only 3.3 V and PVDD – No External Oscillator: Internal Oscillator for Automatic Rate Detection – Surface-Mount, 48-Pin HTQFP Package – Thermal and Short-Circuit Protection – 106-dB SNR, A-Weighted – AD, BD, and Ternary Modulation – Up to 90% Efficient – PWM Level Meter to Measure the Digital Power Profile • Benefits – EQ: Speaker Equalization Improves Audio Performance – Two-Band DRC: Dynamic Range Compression. Can Be Used As Power Limiter. Enables Speaker Protection, Easy Listening, Night-Mode Listening – Autodetect: Automatically Detects Sample- Rate Changes. No Need for External Microprocessor Intervention 2 Applications • LCD TV, LED TV, Soundbar 3 Description The TAS5727 is a 25-W, efficient, digital-audio power amplifier for driving stereo bridge-tied speakers. One serial data input allows processing of up to two discrete audio channels and seamless integration to most digital audio processors and MPEG decoders. The device accepts a wide range of input data and data rates. A fully programmable data path routes these channels to the internal speaker drivers.
