SAMP-300 Dual Core TPA3255 HiFi 2-Channel Power Amplifier Board 600W+600W Automatic Energy-saving Version

SAMP-300 Dual Core TPA3255 HiFi 2-Channel Power Amplifier Board 600W+600W Automatic Energy-saving Version

Description:
- SAMP-300 energy-saving version, when playing music, if the user leaves, there is no music output for a long time (such as using Bluetooth audio source, if the customer leaves with their phone, there will be no playing music). If this process takes more than 1 minute, the board enters standby mode, and the static power consumption is reduced from over 5W to 0.5W, a decrease of more than 10 times. The heat dissipation temperature is equal to room temperature, which not only saves energy but also extends the life of electronic components.

- TPA3255 is a high-performance Class D power amplifier that boasts Class D efficiency and delivers truly high-end sound quality. This device features advanced integrated feedback design and proprietary high-speed gate driver error correction function (PurePath Ultra HD). This technology enables the device to maintain ultra-low distortion throughout the entire audio frequency band while showcasing perfect sound quality. This device operates in AD mode, with a maximum output of 600Wx2/2R or 300Wx2/4 ohms and a 200Wx2/8 ohms load, and features a unique 2VRMS analog input interface that supports seamless connection with high-performance DACs such as PCM5242 for TI. In addition to excellent audio performance, TPA3255 also has two major advantages: high power efficiency and ultra-low power idle loss (less than 2.5W). This can be achieved through an 85mR MOSFET and an optimized gate driver scheme. This scheme can significantly reduce idle losses compared to traditional discrete implementation schemes.

Features:
- Using two original power amplifier modules for TI-TPA3255, the output power separation is much better than that of a single chip.
- The front-end differential input circuit adopts boost technology, which provides a stronger dynamic listening experience than the official single 12V circuit.
- Full screen shielded low loss sealed inductor, imported filtering capacitor.

SAMP-300 Mode Description:
- Automatic energy-saving mode: If there is no music output from the amplifier board for more than 1 minute, the board enters standby mode, and the static power consumption is reduced to one tenth of the original.
- Normal mode: normal operation, whether there is signal input or output, it is in normal working state, and automatic energy-saving is turned off.

Specification:
- Output power: 600W+600W/2ohms; 315W+315W/4ohms; 200W+200W/8ohms
- Frequency response: 20Hz - 30kHz
- THD+N: 0.006% at 1W/4; <0.01% when clipped
- Power supply voltage: 19V - 52V
- PCB size: 138 x 128mm
- Net weight: about 339g

Package Included:
- 1 x Power Amplifier Board

Precaution:
- The higher the input power supply, the greater the power supply current, and the greater the output. The power test was conducted at a power supply of 50V. If replaced with a 24V 36 low-voltage power supply, the output power will decrease accordingly.
