#define OPAMP_PGA_CONNECT_INVERTINGINPUT_IO0_BIAS   OPAMP_CSR_PGGAIN_3

在PGA模式下，反相输入端连接到VINM0

• 输入信号在VINM0上，偏置在VINPx上：负增益
• 偏置在VINM0上输入信号在VINPx上：正增益

#define OPAMP_PGA_CONNECT_INVERTINGINPUT_IO0_IO1_BIAS   (OPAMP_CSR_PGGAIN_4|OPAMP_CSR_PGGAIN_3)

在PGA模式下，反相输入端连接到VINM0

• 输入信号在VINM0上偏置在VINPx上：负增益
• 偏置在VINM0上输入信号在VINPx上：正增益 并且VINM1也连接用于滤波
