Abstract

Analog signal often sampled by A/D conversion in engineering practice,due to external interference and incorrect circuit design, will cause sample accuracy reduce. In order to rejection interference, first a differential input voltage will be magnified by instrumentation, it can rejection noise first, then input amplify signal to TEXAS INSTRUMENTS's ADS1146, it's programmable gain amplifier(PGA) can magnify signal again and internal digital filter can filtering signal again.TL431 can provide precision programmable reference voltage to ADC in order to improve converter accuracy. Finally using software algorithm to reduce interference again The test result shows that this design method can make sample data stable and improve converter accuracy, it has practical value.
