ADC12EU050: Ultra-low Power, Octal, 12-bit, 45MSPS
Sigma-Delta Analog-to-Digital Converter
This Evaluation Board is used to evaluate one of the A/D Converter ADC12EU050. The ADC is a 12 bit
converter that provides data at a rate of 45 MHz.
converter that provides data at a rate of 45 MHz.
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.
