Hi All,
I am using TMS320F28377D for my inverter application. I need to use 16-bit ADC to get precise result. I have single ended input signal but 16-bit ADC only used in differential mode. So, my first requirement is to convert single ended signal into differential signal. Kindly suggest circuitry for the same.
I have to maintain constant 1.65 common mode voltage (Because of ADC VREFHI = 3.3V and VREFLO = 0V). For example, My single ended input is 2.2V then my differential signal output should be Vin+ = 2.2V and Vin- = 1.1V.
Vcm = (Vin+ + Vin-)/2 = (2.2 + 1.1)/2 = 1.65V.
The maximum differential input voltage should grater than 3.3V. I have refered THS4531 but its differential input voltage is only 1V. Which IC i should prefer?
Thanks and regards,
Maulik Timbadiya
