Hi,
The output swing of amplifiers is dependent on supply voltage, output load conditions and temperature. The THP210 datasheet provides an output swing of typical ~100mV when using +/-2.5V supply rail supplies, or equivalently ~100mV to 4.9V when using single unipolar supply +5V. This is for the circuit condition, RIN = RFB = 2 kOhm and Rload resistor 10kOhm connected differentially between OUT+ and OUT-. Please note, in this condition the Fully-Differential Amplifier output is saturated to the output rail, outside its linear region. See below typical output voltage swing specification.
If you want to design the circuit for linear performance, I typically use the more conservative output swing conditions provided on the AOL (open-loop gain) specification. For example, the THP210 specifies an output swing of about 0.3V from the supply rails while meeting AOL performance.
Thank you and Regards,
Luis
