Product Number: AD8138ARZ, AD8138
Hi,
I am using the AD8138 ADC driver in my voltage-sensing circuit. Initially, I had output common mode voltage VOCM of 1.25 V. With this, when Vout_Sense = 0, The differential output voltage I get is 2.3 V. However, if I replace the VOCM with 2.5V, I get the desired differential output voltage of 2.5 V.
The datasheet mentions an input voltage range of 1 V t o3.8 V. Does that also apply to output pins (+OUT and -OUT)? Or else, please let me know what I am missing in the datasheet to explain this.
