Product details
Overview
STEVAL-CCA037V1 from STMicroelectronics is a demonstration board designed to evaluate the TS4990IQT 1.2 W Class AB audio amplifier IC in DFN8 package, operating from 2.2 V to 5.5 V supply, delivering 0.1% THD at 1 kHz with 8 Ω load, and featuring active-low standby mode consuming only 10 nA. It supports BTL configuration with fixed 2 V/V gain and configurable single-ended or differential input for portable audio applications.
For engineers reviewing the STEVAL-CCA037V1 datasheet, STEVAL-CCA037V1 pinout, STEVAL-CCA037V1 application, or STEVAL-CCA037V1 equivalent, key selection considerations include its TS4990IQT-based audio evaluation capability, BTL output architecture, thermal/short-circuit protection, and resistor-modifiable gain and input topology.
Technical Context
The board implements the TS4990IQT in bridged-tied-load (BTL) configuration with fixed 2 V/V closed-loop gain, using external resistors R1 and R2 for optional gain adjustment. Input stage supports both single-ended and differential configurations via jumper-selectable routing.
Power management includes active-low STANDBY control with 10 nA quiescent current, while PSRR reaches 62 dB at 217 Hz in grounded mode. Thermal shutdown and short-circuit protection are integrated into the underlying TS4990IQT device.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Base IC | TS4990IQT low-power audio amplifier with Class AB output stage |
| Supply Range | 2.2 V to 5.5 V - enables direct use with single-cell Li-ion or dual-cell alkaline batteries |
| Output Power | 1.2 W @ 5 V, 1 kHz, 8 Ω, THD = 1% - sufficient for small speakers in portable devices |
| Standby Current | 10 nA - allows multi-year battery life in always-on audio monitoring systems |
| PSRR | 62 dB @ 217 Hz - suppresses power supply ripple in noisy embedded environments |
| THD+N | 0.1% @ 1 kHz - meets fidelity requirements for voice and mid-fidelity audio playback |
| Protection | Thermal shutdown + short-circuit protection - prevents damage during fault conditions |

FAQ
What is the primary function of the STEVAL-CCA037V1 board?
The STEVAL-CCA037V1 is a dedicated evaluation platform for the TS4990IQT audio amplifier IC. It provides a fully assembled, tested circuit implementing BTL output with fixed 2 V/V gain, enabling immediate characterization of output power, THD, PSRR, and standby behavior without custom PCB development.
Can the gain and input configuration be modified on this board?
Yes - gain can be adjusted by replacing resistors R1 or R2 per the TS4990 datasheet equations, and the input topology can be switched between single-ended and differential using on-board jumpers, as confirmed in the schematic and user documentation.
Does the board include protection features inherited from the TS4990IQT?
Yes - thermal shutdown and short-circuit protection are implemented via the TS4990IQT itself and remain fully functional on the STEVAL-CCA037V1 board, verified through the device's internal circuitry and documented fault response behavior.
Is the TS4990IQT on this board mounted in its production-qualified package?
Yes - the TS4990IQT is mounted in its standard DFN8 (dual flat no-lead, 2 mm × 2 mm, 0.5 mm pitch) package, matching the production part's mechanical and thermal characteristics as specified in ST's official datasheet and ordering information.
