Dear Sir,
I would like to use ADS1259 for my application, my analog input range is from +2.5V to -2.5V dc. With dual ±2.5V analog power supplies and +5V of digital power supply. So I have the folowing doubt about hardwre circuit
1) If i use the internal 2.5 V reference, then external reference of -2.5 V is also required for the above analog input range ?
2) As I am not using the PGA280 , so at which potential SYNCOUT Pin should be tied. And what should be the resistor value?
3) I am planning to use the THS4521 as a fully differential amplifier, so the REFOUT pin of the ADS1259 can be connected to VCOM pin of THS4521 ?
Thanks & Regards
Sameer R
