TI专家们好，
我们公司想使用LMP91000研发一款产品，在使用过程中，VOUT输出的电压值并不是50%的基准电压（内部参考电压3.3v），然后RE与WE之间的偏压也为0（设置偏压为10%），C1,C2未接电容，是这个对他有些影响吗？不太清楚原因是什么，希望得到您的帮助。代码如下：
#define TI_LMP91000_TIACN_REG_VALUE (0x03) /* default */
#define TI_LMP91000_REFCN_REG_VALUE (0x28) /* default */
#define TI_LMP91000_MODECN_REG_VALUE (0x07) /* default */
uint8_t read_val[2];
uint8_t status = TI_LMP91000_NOT_READY;
//WDTCTL = WDTPW + WDTHOLD; // Stop watchdog timer
//TI_LMP91000_LED_PxOUT |= TI_LMP91000_LED_PIN; // Set LED ON//自己根据实际情况更改，串口输入输出
//TI_LMP91000_LED_PxDIR |= TI_LMP91000_LED_PIN; // Set pin direction is output
I2CSetup(LMP91000_I2C_Address); // Initialize I2C module
//TI_LMP91000_MENB_PxOUT &= ~TI_LMP91000_MENB_PIN; // Enable \MENB Pin，同上
//TI_LMP91000_MENB_PxDIR |= TI_LMP91000_MENB_PIN; // Set pin direction is output
while (status == TI_LMP91000_NOT_READY)
status = LMP91000_I2CReadReg(TI_LMP91000_STATUS_REG); // Read device ready status
LMP91000_I2CWriteReg(TI_LMP91000_LOCK_REG, TI_LMP91000_WRITE_UNLOCK); // unlock the registers for write
LMP91000_I2CWriteReg(TI_LMP91000_TIACN_REG, TI_LMP91000_TIACN_REG_VALUE); // Modify TIA control register
LMP91000_I2CWriteReg(TI_LMP91000_REFCN_REG, TI_LMP91000_REFCN_REG_VALUE); // Modify REF control register
read_val[0] = LMP91000_I2CReadReg(TI_LMP91000_TIACN_REG); // Read to confirm register is modified
read_val[1] = LMP91000_I2CReadReg(TI_LMP91000_REFCN_REG); // Read to confirm register is modified
if ((read_val[0] != TI_LMP91000_TIACN_REG_VALUE) ||
(read_val[1] != TI_LMP91000_REFCN_REG_VALUE)) // test values took effect
while (1); // otherwise error
// lock the registers
LMP91000_I2CWriteReg(TI_LMP91000_MODECN_REG, TI_LMP91000_MODECN_REG_VALUE); // 3-lead amperometric cell
LMP91000_I2CWriteReg(TI_LMP91000_LOCK_REG, TI_LMP91000_WRITE_LOCK);
谢谢
