STMicroelectronics STEVAL-CCA003V1

Overview

STEVAL-CCA003V1 from STMicroelectronics is an evaluation board for the TS4984 low-voltage stereo audio power amplifier, configured in BTL mode with fixed 2 V gain per channel and supporting single-ended or differential input via configurable jumpers and unpopulated resistor/capacitor footprints. It delivers 1 W per channel into 8 Ω at 5 V supply with 100 dB A-weighted SNR and 62 dB PSRR at 217 Hz.

For engineers reviewing the STEVAL-CCA003V1 datasheet, STEVAL-CCA003V1 pinout, STEVAL-CCA003V1 application, or STEVAL-CCA003V1 equivalent, key selection considerations include its QFN16-based TS4984 amplifier core, jumper-configurable input topology, unpopulated filter sites for custom low-pass implementation, and standby current of 10 nA for ultra-low-power audio subsystem validation.

Technical Context

The board implements the TS4984 in bridge-tied-load (BTL) configuration with fixed gain of 2 V/V per channel, using external resistors R1/R8 and R2/R6 to set feedback. Input stage supports both single-ended (via R3/R6/C3/C5 locations) and differential (requiring R4/R7 modification) operation.

Thermal performance leverages the QFN16 4×4 mm package's exposed pad; unpopulated C1/C6 positions allow integration of external low-pass filters, while Cn1–Cn8 decoupling capacitors ensure stable 2.2–5.5 V operation with near-zero pop-and-click behavior during power-up/down.

FAQ

What is the primary function of the STEVAL-CCA003V1 evaluation board?

The STEVAL-CCA003V1 is a dedicated evaluation platform for the TS4984 stereo audio power amplifier. It provides a fully assembled, tested circuit implementing BTL output with fixed 2 V gain per channel, configurable input topology (single-ended or differential), and unpopulated filter sites for customization. Its purpose is hardware-level validation of audio performance, power efficiency, and system integration under real supply and load conditions.

Can the gain of the TS4984 on this board be adjusted?

Yes, the BTL gain is set to 2 V/V by default using R1/R8 and R2/R6, but it can be modified by replacing those resistors. The board schematic shows R1/R8 for left-channel feedback and R2/R6 for right-channel feedback, enabling independent gain tuning. Gain adjustment requires soldering changes and recalculating resistor values based on the TS4984's internal feedback architecture and gain equation.

Does the board support differential input configuration?

Yes, the board supports differential input via modification: R4 and R7 must be populated (and R3/R6 removed or left unpopulated) to configure the input stage for differential operation. The unpopulated footprints for R3/R6 and C3/C5 provide physical layout flexibility, allowing users to route balanced signals directly to IN+L/IN−L and IN+R/IN−R without redesigning the PCB.

Is the STEVAL-CCA003V1 still in active production?

No, the STEVAL-CCA003V1 is marked as obsolete in ST's official documentation (Rev 1, January 2008). While functional for legacy design validation and educational use, it is not recommended for new designs. ST no longer manufactures or supports this board, and replacement parts like the TS4984 IC itself may also face end-of-life constraints; newer alternatives such as the TS4962 or TDA7388 should be evaluated for current projects.
