STMicroelectronics STEVAL-CCA019V1

Overview

STEVAL-CCA019V1 from STMicroelectronics is a demonstration board for the TS4982 stereo audio power amplifier IC, enabling evaluation of 2 W/channel speaker drive into 4 Ω and 125 mW ground-referenced headphone output into 16 Ω, with configurable 3D enhancement, four-step gain control, and PC-beep detection - used in notebook and portable audio system development.

For engineers reviewing the STEVAL-CCA019V1 datasheet, STEVAL-CCA019V1 pinout, STEVAL-CCA019V1 application, or STEVAL-CCA019V1 equivalent, this board provides validated reference design, thermal protection verification, THD+N measurement setup, and dual-path (speaker + headphone) simultaneous drive validation under single 5 V supply operation.

Technical Context

The board implements the TS4982 in its native 32-pin 5 × 5 mm QFN package, supporting independent standby control to enable concurrent speaker and headphone driver operation. It integrates all required decoupling (1 µF and 330 nF ceramics), gain-setting resistors (10 kΩ, 100 kΩ), and jumpers for digital input configuration (G0/G1, 3D0/3D1, HDEN, SPKREN).

Signal routing separates left/right speaker paths (LOUT+/LOUT−, ROUT+/ROUT−) and headphone paths (LHP/RHP), with dedicated PVCC/PVSS rails and HPVCC for headphone biasing. The BEEP input accepts TTL-level PC alert signals, and pop/click suppression is implemented via internal circuitry verified on-board.

FAQ

What is the primary function of the STEVAL-CCA019V1?

The STEVAL-CCA019V1 is a demonstration board designed exclusively to evaluate the TS4982 stereo audio amplifier IC. It enables functional validation of dual-path audio output (2 W speaker + 125 mW headphone), 3D enhancement, gain control, PC-beep detection, and protection features under real-world 5 V supply conditions.

Does the board support simultaneous speaker and headphone playback?

Yes. The board implements the TS4982's independent standby mode pin (HDEN/SPKREN), allowing both speaker and ground-referenced headphone drivers to operate concurrently from a single 5 V supply without signal crosstalk or rail conflict.

How are gain and 3D settings controlled on this board?

Gain is set using two digital inputs (G0/G1) routed to jumpers JP4 and JP2; 3D level is selected via 3D0/3D1 inputs on JP1 and JP3. All control signals are TTL-compatible and accessible via header pins for external MCU or logic control during testing.

Are critical passive components populated on the board?

Yes. All essential decoupling capacitors (1 µF and 330 nF ceramics), gain-setting resistors (R2, R3, R4), and input/output coupling caps (C1–C17) are factory-populated. Jumpers (JP1–JP20) allow configuration without soldering, and N.A. positions indicate optional or unused components.
