Touch Screen Digitizer

The AD7843 is a 12-bit successive-approximation ADC with a synchronous serial Interface and low on resistance switches for driving Touch Screens The part operates from a single 2.2 V to 5.25 V power supply and features throughput rates greater than 125 kSPS. The external reference applied to the AD7843 CAN be varied from 1 V to +VCC, while the Analog input range is from 0 V to VREF. The device includes a shutdown mode that reduces the current consumption to less than 1 A. This part is available in a 16-lead 0.15" Quarter Size Outline (QSOP) package and a 16-lead Thin Shrink Small Outline (TSSOP) package. (View the QSOP Package Dimensions.) Also see the AD7843 sister part, which is the AD7873. This part is similar to the AD7843 but has added functionality such as an on-chip Temperature Sensor (-40C to + 85C), on-chip 2.5 V reference and direct battery and touch-pressure measurement.
