Application information
Note:
20/31
The analog signal must be filtered to be very pure. The dataready signal is the acquisition
clock of the logic analyzer. The ADC digital outputs are latched by the octal buffers
74LCX573. All characterization measurements are made with SFSR=1 dB for static
parameters.
