What is the maximum output voltage of the ADA4937 with 3V3 single supply?I have ADS42LB49 and its maximum analog input voltage is 3V, is it safe to use without protection diodes while the ADC is driven by ADA4937 ?
Based on the datasheet of ADA4937 page 5, the maximum output Voltage is 2.5V with Vocm referenced at 1.65V (+Vs/2). This 2.5 V is within the input requirement of ADS42LB49 which is -0.3 to 3 V so you may not need a protection diode. Just be sure that the input voltage of ADA4937 is within 0.3 to 1.2V.
