The EG8403 is a filterless Class-D stereo audio power amplifier designed to provide the performance of a Class-AB amplifier with the efficiency of a Class-D amplifier. It features a low-noise, filterless structure that eliminates the need for traditional output low-pass filters, saving PCB space and system cost. The device is ideal for portable applications, offering up to 90% efficiency and up to 3W of output power into a 4Ω load at 5V supply. This manual is written in Chinese.
| Output Power (4Ω, 5V) | 3W |
|---|---|
| Efficiency | Up to 90% |
| Supply Voltage Range | 2.2V to 5.2V |
| Operating Temperature | -40 to 85°C |
| Thermal Shutdown Temperature | 120°C |
| Package Type | SOP16 Lead-free |
| Total Harmonic Distortion (THD+N) | 0.15% (at 0.5W, 8Ω) |
The EG8403 provides up to 3W of output power under a 4Ω load and 5V supply condition.
No, it is a filterless design that eliminates the need for traditional output low-pass filters.
A ceramic capacitor between 0.47μF and 1.0μF is recommended for the best THD and noise characteristics.
