Product details
Overview
EVAL-TDA7803APSO from STMicroelectronics is an automotive-grade evaluation board for the TDA7803A digital intelligent power amplifier IC, supporting four-channel analog audio output from I²S/TDM digital input, operating from 6 V to 18 V, and featuring full diagnostic capability and I²C control interface.
For engineers reviewing the EVAL-TDA7803APSO datasheet, EVAL-TDA7803APSO pinout, EVAL-TDA7803APSO application, or EVAL-TDA7803APSO equivalent, this board enables rapid validation of TDA7803A-based Class-D amplifier designs in infotainment head units, rear-seat entertainment systems, and ADAS audio warning modules under real battery-voltage conditions.
Technical Context
The EVAL-TDA7803APSO implements hardware-level compatibility with the TDA7808 firmware package, allowing reuse of existing driver stacks and calibration profiles. It routes all TDA7803A digital interfaces (I²S/TDM and I²C), power domains (6–18 V analog supply, 3.3 V logic), and diagnostic outputs (FAULT, CLIP, TEMP) to accessible test points and connectors.
Board-level design includes low-ESR bulk capacitance for transient battery load support, ferrite-bead-filtered power rails, and Kelvin-sense traces for accurate output current monitoring-enabling precise thermal and clipping behavior characterization per channel.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Digital Input Interface | I²S and TDM-compatible bus supporting up to 4-channel 24-bit/96 kHz audio data |
| Analog Output Channels | Four independent Class-D amplifier outputs, each capable of driving 4 Ω or 2 Ω loads |
| Supply Voltage Range | 6 V to 18 V DC - validated for automotive battery operation including cold-crank (6 V) and load-dump (18 V) |
| Control Interface | I²C bus (standard-mode, 100 kHz) for register configuration, status readback, and fault logging |
| Diagnostic Coverage | Real-time reporting of overtemperature, output short-circuit, supply undervoltage, and clipping events via dedicated pins |
| Firmware Compatibility | Hardware-compatible with TDA7808 firmware package - enables shared software development across amplifier variants |

FAQ
Does EVAL-TDA7803APSO support TDA7808 firmware without hardware modification?
Yes. The board's hardware layout and signal routing are fully compatible with the TDA7808 firmware package as confirmed in DB3525 Rev 2. No PCB changes or jumper adjustments are required to run TDA7808 firmware on the TDA7803A device mounted on this board.
What power supply requirements must be met to operate EVAL-TDA7803APSO?
The board requires a stabilized 6–18 V DC source capable of delivering ≥5 A peak current. ST recommends using an automotive battery simulator or lab supply with slew-rate limiting to replicate cold-crank and load-dump transients during validation testing.
Can EVAL-TDA7803APSO be used for EMI compliance pre-scanning?
No. While the board includes basic filtering and layout practices aligned with ST's reference design, it lacks shielded enclosures, controlled impedance routing, and CISPR-25-compliant grounding - making it unsuitable for formal EMI pre-scanning without additional enclosure and filtering modifications.
Is the I²C interface accessible via standard headers for external microcontroller control?
Yes. The I²C clock (SCL) and data (SDA) lines are routed to a 4-pin 2.54 mm pitch header labeled "I2C", with pull-up resistors installed. Logic levels are 3.3 V, compatible with common ARM Cortex-M and automotive MCU GPIOs without level shifting.
