According to ADE7953 datasheet page 21 "CURRENT CHANNEL ADCS" as below,
With the specified fullscale analog input of ±250 mV and a PGA_Ix gain setting of 2, the ADC produces its maximum output code. The ADC output swings between −6,500,000 LSBs (decimal) and +6,500,000 LSBs.
As below calculation is correct?
1) 1LSB=7.69E-8 V (0.5V/6,500,000LSBs)
2) 0.645V(7.69E-8V×8388607) when 0x7FFFFFLSBs
Thank you for your help in advance.
