I have attached a circuit. Since I have to measure the voltage using ADS1248.
Now ADS1248 is connected to second board & it have single supply. (AVDD = DVDD = 3.3V)
Output of INA121 in attached circuit is single ended. So I had used THS4521 to convert it to differential signal.
1. I have selected gain = 1 for THS4521.
2. Ground of both boards is common.
3. I have left Vocm of THS4521 open . Will it put the signal to mid level of supply voltage to that its in Vocm range of ADS1248
or I have to additionally connect 1.67V to THS4521.
