Introduction; Board Assembly - National Semiconductor ADC14DC105 User Manual

1.0 Introduction

This Evaluation Board may be used to evaluate one of
the A/D Converters : ADC12DC080, ADC14DC080,
ADC12DC105, or ADC14DC105. The ADC is one of a
family of 12 and 14 bit dual channel analog to digital
converters that provides data at rates of up to 105MHz.
Further reference in this User's Guide to the
ADC14DC105 is meant to also include the other listed
parts unless otherwise specified
The evaluation board is designed to be used with the
WaveVision5™ Data Capture Board which is connected
to a personal computer through a USB port and running
WaveVision5™ software, operating under Microsoft
Windows. The software can perform an FFT on the

captured data upon command and, in addition to a
frequency domain plot, shows dynamic performance in
the form of SNR, SINAD, THD SFDR and ENOB. The
latest WaveVision hardware and software is available
through the National Semiconductor website:
