The Analog to Digital Converter (ADC) is similar to the ones used in DMMs by Rhode & Schwarz (UDS 5) and Solartron (7150). It’s a Voltage-To-Time converter like other integrating conversion methods, e.g. Dual Slope. This Voltage-To-Time converter circuit, comprising an integrator, a comparator, reference switching, converts the voltage output from the buffer amplifier into… Read more nanoDMM – ADC

INTRODUCTION This Digital Multimeter (DMM) is built from off-the-shelf components around an Arduino Nano without the use of a sophisticated front-end ASIC. This blog enables you to build a practical DMM for the everyday use on your bench. But more importantly you’ll get an understanding about the functionality of a DMM, analog to digital conversion,… Read more nanoDMM
