APPLICATION INFORMATION

16/19

- To keep the capacitive loading as low as

possible at digital outputs, short lead lengths

when routing are essential to minimize currents

when the output changes. To minimize this output

capacitance, buffers or latches close to the output

pins can relax this constraint. It is also helpful to

use 47 to 56 ohms series resistors at the ADC

output pins, located as close to the ADC output

pins as possible.

- Choose component sizes as small as possible

(SMD).

EVAL1401 evaluation board

The characterization of the board has been made

with a fully ADC devoted test bench.

The schematic of the evaluation board is shown

on figure 19. The analog signal must be filtered to

be very pure.

The dataready signal is the acquisition clock of the

logic analyzer.

All characterization measurement has been made

with an input amplitude of +0.2dB for static

parameters and -0.5dB for dynamic parameters
