... APPLICATION INFORMATION OVERVIEW The UTC TS2043 is a 12-bit switched-capacitor Analog-to-Digital (A/D) converter and incorporates four channel inputs, a serial interface, and low on-resistance switches for touch panel.. It supplies from a single supply varying from +2.7V to +5.5V. It requires an external reference, which is directly limiting the input range of the converter. The four-channel multiplexer contained in the circuit decides the input to this converter (See Figure 1) ...

... Serial Interface Once a falling signal applies on /CS pin (active in low), the operation is initiated. After /CS falls, the UTC TS2043 begins to look for a start bit on the DIN input. At the end of the operation the /CS pin should be pulled high, which minimizes supply current if DCLK is left running. ...

... Diagram) Input Channel The input channel configuration of the UTC TS2043 is shown in Table V. The control bits are set via the DIN pin. (see Control byte section). The selected channel is for A/D converter input. Please refer to Figure 5 for detailed input channel multiplexer. For measuring X+ and Y+, Y switches and X switches are turned on respectively. ...
