器件型号：TLV320ADC5140

大家好、我正在通过 I2C 配置 TLV320ADC5140、但我无法使输入通道上电。

我将 IN1P 和 IN2P 配置为 ADC 的两个输入、作为线路输入和信号端。

我正在提供用于配置的脚本、您能帮我找到缺少的配置吗？

附件是 ADC5140的单端配置预设代码、请尝试此操作并查看其是否正常工作。

我还建议下载适用于 ADC5140的 PPC3 GUI、以进行表征和寄存器转储

您好、感谢您添加预设代码。我有几个问题

1) 1)我看到大多数都处于复位值、因此我假设我不需要再次写入它们。尤其是对于系数和 DSP 寄存器、因为我不使用它们。

2) 2)我对 PWR_CFG 0x75寄存器还有其他问题、在上面的代码中、它设置为0x00、我需要在什么状态为它们加电？

3) 3)我只需要使用两个杂散通道，所以我不需要配置通道3至8，我对吗？

尊敬的 Uma：

是的、我在包含默认值之前连接的寄存器转储。只需连接即可写入器件：

在代码中、激活模式在[w 98 75 60]配置所有寄存器后设置。此外、SDOUT 还具有两个数据插槽"通道"、用于为每个输入启用 I2S 左/右数据、无论是差分输入还是单端输入。通道5：8可保持默认配置、因为 IN3x 和 IN4x 被禁用
