Hello Eric,
I want to ensure that I know that I know the input signal properly.
Eric Sun 说: amplitude is peak-to-peak 0.5V to 12V, and the modulation ratio is 6:1 to 2:1.
The minimum 0.5Vpp for high bit and (0.5V/6) = 0.83Vpp for low bit
The maximum…
Part Number: ADC3444 For my design, I measured the ADC3444 chip. After powering on, without any program control, both AVDD and DVDD are 1.8V, which is correct, but the VCM pin reads -0.4V, which does not match the datasheet (the datasheet states it should…
