Product details

Overview

STEVAL-CCA009V1 from STMicroelectronics is a high-performance stereo headphone driver demonstration board built around the TS4601B IC, designed for audio evaluation in space-constrained portable devices. It delivers 0.9 V_rms into 16 Ω and 1.6 V_rms into 10 kΩ across 2.9–5.5 V supply, supports I²C-controlled digital volume (−60 dB to +4 dB in 64 steps), and features capacitor-less outputs with common-mode sense for jack noise suppression.

For engineers reviewing the STEVAL-CCA009V1 datasheet, STEVAL-CCA009V1 pinout, STEVAL-CCA009V1 application, or STEVAL-CCA009V1 equivalent, this board enables rapid validation of low-power, high-PSRR (107 dB @ 217 Hz), A-weighted SNR 101 dB headphone driver performance in battery-powered audio systems with I²C configurability and independent channel shutdown.

Technical Context

The board implements the TS4601B's fully differential analog input architecture and capacitor-less Class-AB output stage, eliminating bulky DC-blocking capacitors while maintaining rail-to-rail output swing. Its integrated common-mode sense (CMS) pin actively rejects jack-induced parasitic noise, and the on-board RS232-to-I²C converter enables PC-based volume and mode control via standard serial interface.

Power management is optimized for portable use: quiescent current is 4.8 mA typical at 3.0 V, and standby current drops to ≤2 µA. The design supports dual-channel independent shutdown, allowing dynamic power gating per channel without affecting the other.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	2.9 V to 5.5 V - Enables direct operation from single-cell Li-ion or dual-cell alkaline batteries.
Output Voltage (16 Ω)	≥0.9 V_rms - Delivers sufficient drive level for standard consumer headphones without external amplification.
PSRR @ 217 Hz	107 dB - Rejects switching noise from PMICs or DC/DC converters commonly found in portable systems.
A-weighted SNR	101 dB - Ensures high-fidelity audio playback with minimal audible background noise.
I²C Volume Control	−60 dB to +4 dB in 64 steps - Provides precise, software-adjustable gain matching for varying source levels and headphone sensitivities.
Standby Current	≤2 µA - Minimizes battery drain during system sleep modes in always-on audio interfaces.

FAQ

What is the primary function of the STEVAL-CCA009V1 board?

The STEVAL-CCA009V1 is a demonstration board for evaluating the TS4601B stereo headphone driver IC. It provides a complete, tested hardware platform-including I²C interface circuitry, RS232-to-I²C converter, and optimized layout-for validating audio performance, power efficiency, and capacitor-less output operation in real-world portable applications.

Does the board support standalone operation without a PC?

Yes - the board can operate standalone using external I²C master control (e.g., MCU). However, the included RS232-to-I²C converter allows immediate PC-based evaluation via terminal software, enabling quick volume adjustment, channel enable/disable, and mode configuration without custom firmware development.

Can the TS4601B on this board drive 32 Ω headphones effectively?

Yes - although characterized for 16 Ω and 10 kΩ loads, the TS4601B's output stage delivers ≥0.9 V_rms into 16 Ω and maintains full rail-to-rail swing capability. At 32 Ω, output voltage remains well above 0.7 V_rms, supporting >10 mW into typical 32 Ω headphones at 3.3 V supply, confirmed by TS4601B's datasheet load regulation curves.

Is the STEVAL-CCA009V1 still in active production?

No - STMicroelectronics has marked STEVAL-CCA009V1 as obsolete (per Doc ID 18258 Rev 1, November 2010). Aetrix Electronics holds remaining legacy stock for design continuity and legacy system support, but no new manufacturing or long-term supply commitment exists from ST.
