STMicroelectronics STEVAL-CCA008V1

Overview

STEVAL-CCA008V1 from STMicroelectronics is a demonstration board for the TS4998 2×1 W differential-input stereo audio amplifier IC, operating from 2.7 V to 5.5 V supply, delivering 1 W per channel into 8 Ω at 5 V with 106 dB(A) SNR and 10 nA standby current per channel, used in portable audio playback systems.

For engineers reviewing the STEVAL-CCA008V1 datasheet, STEVAL-CCA008V1 pinout, STEVAL-CCA008V1 application, or STEVAL-CCA008V1 equivalent, this page provides verified board-level specifications, functional block context, power delivery capability, thermal protection behavior, and evaluation-ready interface details.

Technical Context

The board implements the TS4998 in BTL (bridge-tied load) configuration, enabling 1 W RMS per channel into 8 Ω without output coupling capacitors. It supports independent channel control via dedicated STBYL and STBYR pins, each reducing quiescent current to <10 nA in shutdown mode.

Power supply rejection is 80 dB at 217 Hz with grounded inputs; startup time is 45 ms typical; and pop/click suppression circuitry eliminates audible transients during power-up/down. Gain is set externally via resistor dividers on LIN+/LIN− and RIN+/RIN− inputs.

FAQ

What is the primary purpose of the STEVAL-CCA008V1 board?

The STEVAL-CCA008V1 is a ready-to-use demonstration board for evaluating the TS4998 stereo audio amplifier IC. It provides fully assembled circuitry including input filtering, gain-setting resistors, BTL output stage, thermal pad layout, and dual-channel standby control - enabling immediate functional verification and audio performance benchmarking without custom PCB design.

Does the board support differential input operation as specified for the TS4998?

Yes. The board implements true differential input topology for both left and right channels using matched RC networks (Cin1–Cin4, Cs1–Cs2, Cn1–Cn8) and precision 24 kΩ gain-setting resistors (R1–R4), preserving the TS4998's specified 106 dB SNR and 80 dB PSRR under balanced signal conditions.

Can the output power be increased beyond 1 W per channel on this board?

No. The board is optimized for the TS4998's rated 1 W per channel into 8 Ω at 5 V. Output power is constrained by the IC's internal current limit, thermal design (QFN16 exposed pad), and passive component ratings. Higher power would require different IC selection, heatsinking, and PCB layout - not supported by this fixed-evaluation platform.

Is thermal shutdown functionality accessible or observable on the STEVAL-CCA008V1?

Yes. Thermal shutdown is implemented internally in the TS4998 and activates automatically when die temperature exceeds safe limits. While no external indicator LED or test point is provided, the board's QFN16 footprint includes an exposed thermal pad soldered to a large copper pour - enabling direct IR thermography or contact temperature measurement during sustained 1 W operation to validate thermal response.
