Evaluation boards for audio amplifiers are specialized hardware platforms designed to test, validate, and develop audio amplifier circuits. These boards provide engineers with a controlled environment to measure performance metrics such as output power, efficiency, and signal fidelity. They play a critical role in modern audio system design by accelerating prototyping, reducing development risks, and ensuring compliance with industry standards. Applications span consumer electronics, automotive audio systems, and professional sound equipment.
| Type | Functional Features | Application Examples |
|---|---|---|
| Stereo Amplifier Boards | Dual-channel output, low THD+N, adjustable gain | Home theater systems, portable speakers |
| D-Class Amplifier Boards | High efficiency (>90%), PWM modulation, thermal protection | Car audio systems, battery-powered devices |
| Headphone Amplifier Boards | Low noise floor, impedance matching, volume control | Smartphones, studio headphones |
| Digital Audio Amplifier Boards | Integrated DSP, I2S interface, EQ customization | Smart speakers, IoT audio devices |
Typical evaluation boards consist of: - PCB Substrate: Multi-layer FR4 material with impedance-controlled traces - Amplifier IC: Mounted in standard packages (e.g., TSSOP, QFN) - Power Management: DC/DC converters and LDOs for voltage regulation - Connectors: RCA, XLR, or 3.5mm jacks for input/output - Test Points: Probes for measuring voltage, current, and signal integrity - Microcontroller Interface: I2C/SPI ports for configuration and debugging
| Parameter | Description | Importance |
|---|---|---|
| Output Power (W) | Continuous RMS power delivery | Determines speaker compatibility |
| Efficiency (%) | Power conversion ratio | Impacts thermal design and battery life |
| THD+N (%) | Total harmonic distortion + noise | Measures audio fidelity |
| Frequency Response (Hz) | Operational bandwidth (20Hz-20kHz typical) | Defines audible range coverage |
| PSRR (dB) | Power supply rejection ratio | Indicates noise immunity |
| Manufacturer | Key Product | Features |
|---|---|---|
| Texas Instruments | PCM5122EVM | DAC + headphone amplifier, 120dB SNR |
| STMicroelectronics | STEVAL-CCA026V1 | Digital input, 2x15W stereo output |
| Analog Devices | AD2428W-EVALZ | Automotive-grade, 4-channel amplifier |
| Maxim Integrated | MAX98357AEVKIT | Class D, 15W mono with H-bridge output |
