UTC7106 A/D Converter

ANALOG SECTION Figure 1 shows the Analog Section for the UTC 7106. Each measurement cycle is divided into three phases. They are(1) auto-zero(A-Z), (2)signal integrate (INT)and (3)de-integrate(DE). AUTO-ZERO PHASE During auto-zero three things happen. First, input high and low are disconnected from the pins and internally shorted to analog COMMON. Second, .
