Note: We have tested it. We ship the board after full test. It also works well with 12V DC power. However, we suggest to use DC 14V-39V power supply if possible.
Specification:
The following table lists all typical data of the amplifier board. For full specification, please refer to the datasheet of ST’s TDA7498 chip.
TA = 25 °C, fIN = 1 kHz sine wave, RL= 6Ω, VCC = 36V. (Unless otherwise stated)
