Brief Introduction：
This amplifier is a state-of-the-art dual channel Class-D audio amplifier which integrates ST’s TDA7492 as the driver. This amplifier is capable of delivering dual-channel amplification with each channel up to 25W. High quality and high performance components are used making this amplifier high-quality amplifier. Powered by 14V to 19V supply, it can be used in many applications like Background Music Systems. It also features thermal protection. In addition, on-board heat sink ensures excellent heat dissipation.
Features:
L-style Aluminium Bracket:
To improving the connection and measurement efficiency and saving the cost on installations, Sure Electronics provides a L-type aluminium bracket for audio amplifier boards. The aluminium bracket supports vertical and horizontal installtion ways to satisfy different installation requirements. With 4 M3 screw lock standoffs and 2 M3 pre-drilled mounting holes, audio amplifier boards could be installed on the bracket easily.
Following table lists all typical data of the Amp board. For full specification, please refer to the
data sheet of ST’s TDA7492 chip.
TA = 25 °C, fIN = 1 kHz sine wave, RL= 8Ω, VCC = 25V. (Unless otherwise stated)
