摘要：
An improved dual slope integrating analog-to-digital converter for use in a Digital Multi-Meter includes an input portion, an A/D core portion, and a digital portion. The A/D core portion includes an auto zero function capability for automatically compensating for any existing offset voltages in various measurement modes such as voltage, resistance, or current measurement modes. The improved A/D converter of the present invention operates at high speed and with high resolution.
