Input voltage and A/Ded data at AD_Range = 1 (ie. A/D data = -2,047 ~ 2,047)

A/Ded data is a 12 bits signed data which A/D[11] shows the sign of A/Ded data as follow :

Case 1 : If A/D[11] = 0,

Input voltage = + A/D[10:0] / 2048 *VR (V) / PGA gain

Case 2 : If A/D[11] = 1,

Input voltage = - A/D[10:0] / 2048 *VR (V) / PGA gain

Note: A/Ded data (signed 12 bits) = Converts into decimal value

Executing RR_AD command could read out the contents of A/D register to DOUT pin. Please refer

to section 1-5. for the operation of RR_AD command.
