For the Above circuit the Output of AD8232 is 0.9V offset +( Diff o/p * system gain ). This output is fed to the ADPD107 PD input configured in TIA ADC mode.
or should i consider below equation?.
Vout of TIA = Tia_Bias - Iin * Rf and get Iin
which is the right way ?.
what is the exact output voltage from the ADC for "Measuring Voltages Using the Current Inputs(page 47 of ADPD105/7 data sheet)"?.
Kindly guide me in this regard Optical Sensing@kevin
Thanks in advance.
