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). In addition, an
external clock is also required.
OPERATION OF 24-CLOCKS
The UTC TS2043 communicates with microprocessors or digital signal processors through a synchronous
serial interface. For a total 24 clock cycles on the DCLK input, three serial communications are needed to complete
one conversion. (See Figure 2)
