AFE4300 ADC

Other Parts Discussed in Thread: AFE4300

Hello, i have questions regarding to ADC two's complement output format.

As described in the Table 1 of the datasheet, +FS/2^15 mV = 0001h, -FS/2^15 mV = FFFFh and 0 mV = 0. For example, if FS = 2^15mV, then +1mV = 0001h and -1mV = FFFFh.

So what will be the ADC code if the input voltage is +0.5mV or -0.5mV ?

If the input voltage is 1.5mV, will the ADC code be 0001h or 0002h?

If input voltage is -1.5mV, then what will be the code?

Because it seems to me that the ADC code 0000h has double input voltage range comparing to other codes (from -FS/2^15 to FS/2^15 is FS/2^14 mV)

Thank you
