improve high frequency bypassing and reduce
harmonic distortion.
- Proper termination of all inputs and outputs is
needed; with output termination resistors, the
amplifier load will be only resistive and the stability
of the amplifier will be improved. All leads must be
wide and as short as possible especially for the
analog input in order to decrease parasitic
capacitance and inductance.
- To keep the capacitive loading as low as
possible at digital outputs, short lead lengths of
routing are essential to minimize currents when
the output changes. To minimize this output
capacitance, buffers or latches close to the output
pins will relax this constraint.
- Choose component sizes as small as possible
(SMD).
EVAL1201 evaluation board
The characterization of the board has been made
with a fully ADC devoted test bench as shown on
Figure 11. 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 have been
made with:
- SFSR=+0.5dB for static parameters.
- SFSR=-0.5dB for dynamic parameters.
