Hello:
Because we use the commercial module of AD9238. The schematic for ADC input is as below. Do you think if my input range is +/-1V. It still need ADA4930 to convert them? it seem ADC_AVIN- has been connected to GND. So for the schematic below, could it accept negative input voltage, such as -0.5V. If not, what chip do you recommend to solve that problem, because the negative output of ADA4930 could not be terminated to GND. Thanks!
