Part Number: LM98640QML-SP Hi, For a logical 1 on the SDO pin, the datasheet specifies a typical voltage of 1.93V and a minimum voltage of 1.8V. However, to me it seems like the serial interface was designed for 3.3V logic, since the minimum input voltage for a logical 1 on the SCLK, SEN, SDI and CLPIN pins is 2.0V. Furthermore, when observing the SDO output voltage on an oscilloscope, I get a value near 3.3V, not a value near 1.93V. Can you comment on the apparent contradiction? Thanks, Bradley
