Product details

Overview

STEVAL-CCA028V1 from STMicroelectronics is a 10 W + 10 W dual-channel Class-D audio amplifier demonstration board based on the TDA7491P IC, operating from a single 5–18 V supply, delivering 9.5 W per channel into 8 Ω at 12 V with 10% THD, and featuring filterless operation, differential inputs, and integrated thermal/short-circuit protection.

For engineers reviewing the STEVAL-CCA028V1 datasheet, STEVAL-CCA028V1 pinout, STEVAL-CCA028V1 application, or STEVAL-CCA028V1 equivalent, this board enables rapid validation of gain configuration (20/26/30/32 dB), standby/mute control, external clock synchronization, and heatsink-free operation in compact audio systems.

Technical Context

The board implements the TDA7491P in BTL (Bridge-Tied Load) topology, supporting both single-ended and differential analog inputs via configurable jumpers. It uses no output LC filters-relying on spread-spectrum modulation and optimized layout for EMI compliance.

Power delivery includes dedicated PVCC/PVCCA/PVCCB rails, separate power grounds (PGNDA/PGNDB), and diagnostic pins (DIAG, SVR) for fault reporting. Synchronization input (SYNCLK) allows multi-board timing alignment without jitter accumulation.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Power	10 W + 10 W continuous into 6 Ω @ 11 V, 10% THD - enables full-range stereo playback in compact enclosures without forced cooling.
Supply Voltage Range	5–18 V single supply - supports battery-powered (e.g., 2S–4S Li-ion) and adapter-fed audio systems without rail splitting.
Efficiency	η = 90% - reduces thermal load on PCB and eliminates need for heatsinks in ≤10 W/channel designs.
Gain Settings	20 dB / 26 dB / 30 dB / 32 dB (fixed, jumper-selectable) - matches varied line-level or DAC output amplitudes without external op-amps.
Input Configuration	Differential or single-ended via hardware jumpers - suppresses common-mode noise in noisy environments (e.g., automotive infotainment).
Protection Features	Thermal shutdown, short-circuit detection, and mute-controlled soft-start - prevents speaker damage and pop-noise during power sequencing.

FAQ

What input signal types does STEVAL-CCA028V1 accept?

The board accepts either differential or single-ended analog audio inputs, selected via onboard jumpers (JP1–JP4). Differential mode uses INPA/INNA and INPB/INNB pairs for noise rejection; single-ended mode routes signals through INPA and INPB only, with referenced ground paths defined by SGND and SUB_GND.

Does STEVAL-CCA028V1 require an external LC filter?

No. The TDA7491P IC on this board uses filterless modulation architecture, eliminating external output chokes and capacitors. EMI is managed through spread-spectrum switching and optimized PCB layout - verified per EN55032 Class B limits in the original ST reference design.

How is gain configured on this demonstration board?

Gain is set using two 2-position DIP switches (SW1 and SW2), selecting among four fixed values: 20 dB, 26 dB, 30 dB, or 32 dB. Switch positions directly configure internal resistor networks inside the TDA7491P - no firmware or external components are needed for gain adjustment.

Can STEVAL-CCA028V1 be synchronized with other Class-D boards?

Yes. The SYNCLK input (Pin 25 of U1) accepts an external 200–500 kHz clock signal to align switching frequencies across multiple boards, reducing beat frequencies and inter-board EMI coupling - critical for multi-channel active speaker arrays and distributed audio systems.
