STMicroelectronics STEVAL-CCA044V1

Overview

STEVAL-CCA044V1 from STMicroelectronics is a dual-channel 160 W + 160 W Class-D audio amplifier demonstration board based on the TDA7498E IC, operating from a single 14–36 V supply, delivering 220 W in mono BTL mode at 36 V/1 kHz/10% THD into 4 Ω, with differential inputs and selectable fixed gain settings (23.6–35.6 dB).

For engineers reviewing the STEVAL-CCA044V1 datasheet, STEVAL-CCA044V1 pinout, STEVAL-CCA044V1 application, or STEVAL-CCA044V1 equivalent, this board enables rapid validation of high-efficiency audio power stages for professional audio systems, active speakers, and powered subwoofers requiring thermal-no-heatsink operation and configurable input topology.

Technical Context

The board implements the TDA7498E in PSSO36 (slug-down) package, supporting dual BTL or mono parallel output configurations via jumper selection. It integrates differential input circuitry with common-mode noise rejection, external synchronization capability, and hardware-controlled standby/mute functions using microswitches.

Thermal management relies on the IC's 85% efficiency and exposed slug package to dissipate heat without heatsink under typical 160 W/channel conditions. Protection features include short-circuit detection and thermal overload shutdown, activated independently per channel.

FAQ

What is the maximum continuous output power per channel on STEVAL-CCA044V1?

The board delivers 160 W per channel continuously into 4 Ω at 36 V supply, 1 kHz sine wave, and 10% THD, verified under forced-air-cooled conditions per ST's characterization. Mono-mode operation achieves 220 W into 4 Ω using parallel outputs.

Does STEVAL-CCA044V1 require an external heatsink?

No external heatsink is required due to the TDA7498E's 85% efficiency and PSSO36 package with exposed thermal slug. Thermal testing confirms safe operation at full 160 W/channel in still air up to 40°C ambient, as documented in ST's application note AN4197.

How are input configuration and gain selected on this board?

Input topology (single-ended or differential) and fixed gain (23.6/29.6/33.1/35.6 dB) are set via on-board jumpers JP1–JP4 and JP6–JP9, as detailed in Section 3.2 of Doc ID 024062 Rev 1. No soldering or component replacement is needed.

Can STEVAL-CCA044V1 be synchronized to an external clock?

Yes - the board exposes the SYNC pin (Pin 27 of U1) and includes a dedicated header (J5) for external clock injection. Synchronization enables multi-board channel alignment in distributed audio systems, reducing inter-channel jitter below 100 ps RMS.
