STMicroelectronics STEVAL-CCA001V1

Overview

STEVAL-CCA001V1 from STMicroelectronics is a mono Class D audio amplifier evaluation board based on the TS4962MEIJT flip-chip IC, operating from 2.4 V to 5.5 V supply, delivering 2 V/V fixed gain, with 10 nA standby current, 63 dB PSRR at 217 Hz, and 5 ms startup time for portable audio applications.

For engineers reviewing the STEVAL-CCA001V1 datasheet, STEVAL-CCA001V1 pinout, STEVAL-CCA001V1 application, or STEVAL-CCA001V1 equivalent, this board enables rapid validation of differential-input/output Class D amplification in space-constrained, battery-powered systems requiring low quiescent power and pop/click suppression.

Technical Context

The board implements the TS4962M's fully-differential architecture with internal common-mode feedback that maintains output bias at VCC/2 across varying DC input common-mode voltages-ensuring maximum voltage swing and output power. Its flip-chip-to-DIP adapter allows breadboard-friendly evaluation of the 10-pin flip-chip die.

It integrates thermal and short-circuit protection, uses external 150 kΩ resistors for input biasing, and relies on 100 nF ceramic capacitors (C2, C3) and a 2.2 µF/10 V electrolytic (C1) for stable PWM output stage operation and supply decoupling.

FAQ

What is the primary function of the STEVAL-CCA001V1 board?

The STEVAL-CCA001V1 is a dedicated evaluation platform for the TS4962MEIJT mono Class D audio amplifier. It provides a complete, tested circuit-including flip-chip-to-DIP adapter, input biasing network, output filtering, and power decoupling-to validate audio performance, power efficiency, and startup behavior in real-world portable systems.

Does the board support adjustable gain?

No. The board implements a fixed 2 V/V gain via internal configuration of the TS4962MEIJT, as confirmed by the schematic and data brief. Gain is not user-adjustable through external resistors or jumpers; it is set by the IC's internal architecture and cannot be modified without replacing the amplifier IC.

Can the STEVAL-CCA001V1 drive 4 Ω or 8 Ω speakers directly?

Yes. The TS4962MEIJT on this board is rated for 1.5 W into 8 Ω and 2.5 W into 4 Ω at 5 V supply, per ST's characterization. The board's layout and component selection-including output LC filter and thermal pad design-support direct connection to standard miniature speakers without external buffering.

Is an external oscillator required for operation?

No. The TS4962MEIJT integrates a 150 kHz internal oscillator, as shown in Figure 1 of the data brief. The board requires no external clock source; all timing generation is self-contained within the IC, simplifying system integration and reducing component count.
