Abstract
U ovome diplomskom radu je izveden voltmetar koji mjeri napon od 0 do 5V. Napon se utvrđuje difrencijalnom tehnikom, koja uspoređuje referentni napon s nepoznatim naponom. Instrument se sastoji od dva dijela od ADC pretvornika i mikroupravljača Atmega16. Rezultat mjerenja mikroupravljač šalje na LCD i na USB port računala pomoću UART komunikacije. Za ADC pretvorbu korišten je LTC2400 pretvornik koji ima 24 bitnu rezoluciju i radi pomoću delta sigma modulacije. Instrument realiziran je na PCB pločici s internim referentnim naponom. Analiziran je programski dio sklopa i pojedine funkcije sklopa. Utvrđenja je greška sklopa koja iznosi 57 ppm. Sklop kao takav i s relativnom niskom cijenom reda 20$ primjeniv je u niz rješenjima, npr. senzorici, komunikacijskoj tehnici, mjerenjima težine, temperature, tlaka i sličn

The purpose of this Master Thesis was to design and build a voltmeter for the measurement in the range between 0 and 5V. The voltage is determined by a differential method, which compares a reference voltage with an unknown voltage. The instrument consist of two parts, an ADC converter and a microcontroller Atmega16. The resulting measurement is then sent to a PC USB port through UART communication, and shown ond the voltmeter´s display. For the AD Converter, a LTC2400 converter has been used with a 24 bit resolution and using an delta sigma moudulation. The instrument has been realised on a PCB board with internal reference voltage. Some functions and the embedded software have been analysed. The error of this instrument is 56.7 ppm. The device, with a low production cost of about 20$ is applicable in a variety of technical solutions, i. e. sensors, communication technique, measuring weight, temperature and pressure, etc.
