STMicroelectronics STEVAL-CCA002V1

Overview

STEVAL-CCA002V1 from STMicroelectronics is an evaluation board for the TS4994 low-voltage differential audio power amplifier, designed to demonstrate 1 W output into 8 Ω at 5 V supply with 0.1% THD+N at 1 kHz, ultra-low 10 nA standby current, and 100 dB PSRR at 217 Hz in grounded mode. It supports capacitor-coupled or common-mode feedback input configurations via Cn3/Cn4 jumpers.

For engineers reviewing the STEVAL-CCA002V1 datasheet, STEVAL-CCA002V1 pinout, STEVAL-CCA002V1 application, or STEVAL-CCA002V1 equivalent, this board enables rapid validation of differential audio amplification in space-constrained portable systems requiring low-noise, low-pop performance and flexible gain configuration.

Technical Context

The board implements the TS4994 in DFN10 package with fixed 1 V/V differential gain, configurable via external resistor network (R1–R4). Input coupling mode is selected by Cn3/Cn4 jumpers, enabling either AC-coupled operation (with -3 dB cutoff determined by R1/C1 and R3/C2) or common-mode feedback topology.

Thermal and short-circuit protection circuits are fully implemented per TS4994 specifications. Power supply range is 2.5 V to 5.5 V, supporting single-cell Li-ion and dual-cell alkaline battery operation while maintaining <0.1% distortion and near-zero pop/click during turn-on/standby transitions.

FAQ

What is the primary function of the STEVAL-CCA002V1 evaluation board?

The STEVAL-CCA002V1 is a dedicated evaluation platform for the TS4994 differential audio power amplifier. It provides a complete, tested implementation including input coupling selection (capacitor-coupled or common-mode feedback), fixed 1 V/V gain, thermal protection, and layout-optimized DFN10 mounting - enabling immediate functional validation and audio performance measurement without custom PCB development.

Can the gain of the TS4994 on this board be modified?

Yes. Although the board ships with R1–R4 configured for 1 V/V differential gain, the schematic explicitly permits gain adjustment by replacing resistors R1–R4 per Equation 1 (Av = R2/R1 = R4/R3). This allows users to scale gain up to ±10 V/V depending on resistor matching and stability constraints, without altering the core amplifier IC or layout.

Does STEVAL-CCA002V1 support single-ended input signals?

No. The board is designed exclusively for differential input operation, consistent with the TS4994's native architecture. Input configuration options - selected via Cn3/Cn4 jumpers - are limited to differential capacitor-coupled or differential common-mode feedback modes. Single-ended-to-differential conversion requires external circuitry not included on this board.

Is the TS4994 on this board automotive qualified?

No. The TS4994 used on STEVAL-CCA002V1 is not specified as automotive grade, and the evaluation board itself carries no AEC-Q100 qualification. ST's documentation explicitly states that non-automotive-grade products like this are intended for consumer and industrial applications only, and must not be deployed in safety-critical or automotive environments without independent validation and risk assessment.
