The datasheet for this part can be found here https://www.ti.com/lit/ds/slas061d/slas061d.pdf.
1. The datasheet shows pin 16 as Rfb but does not explain its purpose. What does it do?
2. Also, there are two outputs on pins 1 & 2, is one of them to be always grounded as shown in Figure 3 and Figure 4? If so, then why even include it and not have just a single output?
3. Is it not possible to connect a voltmeter directly across pin 1 or pin 2 (and GND) to measure the output voltage of the ADC or must an op-amp to convert the current to voltage always be connected at the output?
