Product Description
STMicroelectronics STEVAL-CCA042V1 is a Dual BTL Class-D Audio Amplifier Demonstration Board designed around the TDA7491HV high-power audio amplifier. It supports a wide single-supply voltage range from 5 V up to 18 V and delivers up to 20 W per channel continuous power output with an 8 Ω load at 10% total harmonic distortion (THD), demonstrating high efficiency up to 90% typical.
The device is packaged in a PSSO36 slug-down package allowing heat dissipation without needing a heatsink. The board includes jumpers to configure the amplifier for either single-ended or differential input modes and selectable gain settings of 20 dB, 26 dB, 30 dB, and 32 dB, providing flexibility for different application requirements.
Microswitches on the board enable standby and mute features for power management and audio signal control. Features like differential inputs help minimize common-mode noise, and the amplifier operates filterless, simplifying the external circuitry.
Protection functions including short-circuit and thermal overload safeguards are integrated to ensure robust operation under various conditions. The amplifier can be externally synchronized for applications requiring multiple amplifier channels to operate in sync.
This evaluation board is ideal for engineers and developers in audio electronics design, prototyping, and educational applications, offering a ready-to-use platform for evaluating the TDA7491HV device performance.
The board integrates the TDA7491HV high-power dual BTL class-D audio amplifier. Wide single-supply operation range from 5 V to 18 V. High efficiency with typical 90% power conversion. Selectable gain settings to adapt to different input levels.
Standby and mute functions enabled through microswitches. Filterless design reduces component count and footprint. Built-in short-circuit and thermal overload protection. Configurable input mode with jumpers for signal flexibility.
Perfect for industrial, educational, and audio system development use cases. Explore the full range of audio amplifier development tools and demonstration boards on EnvMart to optimize your audio development projects.
