Design of high precision and high swing multi-site ADC test system

Abstract

Based on V93000 ATE, a test system using external power boost conversion module and programmable gain instrumentation operational amplifier was designed to meet the requirements of mass production of multi-sites ADC with large-swing and high-precision. The theoretical and test results show that the ADC test system can generate 29.4 V ramp and 29.1 V sine wave signals with peak to peak value. The SNR of test signal is better than 105 dB and THD is better than -103 dB, which can meet the test requirements of 16 bit high-precision and ±10 V high input swing multi-sites ADC.
