Product details
Overview
EVAL-TDA7803AFW from STMicroelectronics is an evaluation board for the TDA7803A automotive digital intelligent power amplifier IC, supporting four-channel analog audio output from digital I²S/TDM input, operating from 6 V to 18 V, and featuring full diagnostic capability and I²C control interface.
For engineers reviewing the EVAL-TDA7803AFW datasheet, EVAL-TDA7803AFW pinout, EVAL-TDA7803AFW application, or EVAL-TDA7803AFW equivalent, this board enables rapid validation of TDA7803A-based Class-D amplifier designs in battery-powered automotive infotainment systems with integrated diagnostics and firmware-upgradable functionality.
Technical Context
The board implements the complete signal chain for the TDA7803A IC, including I²S/TDM digital audio input routing, I²C configuration and monitoring interface, analog output filtering, and DC/DC supply conditioning for 6–18 V battery operation. It supports real-time diagnostic reporting via I²C and hardware fault signaling.
Hardware design maintains mechanical and electrical compatibility with the TDA7808 evaluation platform in FW package, enabling reuse of test fixtures and firmware assets across both amplifier generations while preserving layout-defined thermal and EMI performance boundaries.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Digital Input Interface | I²S and TDM-compatible bus, enabling multi-channel time-division multiplexed audio streaming from SoC or DSP sources |
| Analog Output Channels | Four independent Class-D amplifier outputs, each capable of driving 4 Ω or 2 Ω loads with integrated protection |
| Supply Voltage Range | 6 V to 18 V DC, directly compatible with automotive battery rails including cold-crank (6 V) and load-dump (18 V) conditions |
| Control & Diagnostics | Fully implemented I²C interface for register-level configuration, status readback, and fault logging without host processor dependency |
| Hardware Compatibility | Pin- and footprint-compatible with TDA7808 evaluation board in FW package, allowing shared test infrastructure and firmware binaries |

FAQ
Does EVAL-TDA7803AFW support TDA7808 firmware?
Yes - the board is hardware-compatible with the TDA7808 in FW package per ST's DB3525 data brief, enabling direct firmware reuse and shared test infrastructure. No hardware modification is required to run TDA7808 firmware on this board when used with the corresponding IC.
What audio formats does the board accept via I²S/TDM?
The board accepts standard I²S (left-justified, right-justified) and TDM configurations up to 32 slots, supporting sample rates from 32 kHz to 96 kHz and bit depths of 16/24/32 bits as defined by the TDA7803A's digital interface specification.
Is external power supply filtering required?
No - the board integrates input LC filtering and local ceramic decoupling optimized for automotive battery noise, meeting CISPR-25 Class 5 emission limits. Additional filtering is unnecessary unless operating in extreme EMI environments beyond ISO 11452-2 test conditions.
Can this board be used for production audio output?
No - EVAL-TDA7803AFW is strictly an evaluation and development tool, not qualified for automotive production use. Its PCB layout, component selection, and thermal design meet evaluation requirements but lack AEC-Q200 stress screening and PPAP documentation required for series production deployment.
