您好、
请参阅示例配置(这源自数据表中给出的4通道配置):
# # Power up IOVDD and AVDD power supplies keeping SHDNZ pin voltage LOW # Wait for IOVDD and AVDD power supplies to settle to steady state operating voltage range. # Release SHDNZ to HIGH. # Wait for 1ms. # # Wake-up device by I2C write into P0_R2 using internal AREG w 98 02 81 # #Configure the device for 24-bit I2S operation by I2C write into P0_R7 w 98 07 60 # # Enable Input Ch-1 by I2C write into P0_R115 w 98 73 80 # # Enable ASI Output for Ch-1 slots by I2C write into P0_R116 w 98 74 80 # # Power-up ADC, MICBIAS and PLL by I2C write into P0_R117 w 98 75 E0
也可以使用适用于 TAA3040的 PPC3 GUI 推导出所需的配置、我建议客户可以从产品文件夹申请访问 GUI:
