Hello. I used an oscilloscope to measure the voltage of AD9974 horizonal driver outputs(H1、H2、H3、H4).However,I found the voltage is lower than expected.The voltage ranged from -75mV to 622mV,while the expected range should be 0.5V(or lower) to 2.8V(or higer) when setting the HVDD voltage to 3.3V.Why the voltage of horizonal driver is lower than expected?


Thanks in advance.
