Forum Post: Analog input range of AFE5801 when AC coupling is used

Hello,

I fount the analog input range of AFE5801 is –0.3V to MIN (3.6V, AVDD3 + 0.3V). If I have a negative signal, like -0.9V, (0.45 for positive input and -0.45 for negative input), is it mean I CAN NOT use AC coupling?

Thanks.
