The AD7843ARUZ 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 to 5.25V power supply and features throughput rates greater than 125kSPS. The external reference applied to the AD7843 can be varied from 1V to +VCC, while the analog input range is from 0V to VREF. This touch screen digitizer includes a shutdown mode that reduces the current consumption to less than 1µA. It features on-board switches. This, coupled with low power and high speed operation, makes this device ideal.
● 4-wire Touch screen interface
● Ratiometric conversion
● High speed serial interface
● 2 Auxiliary analog inputs
● 1µA Maximum shutdown mode
● Low power consumption
● Versatile serial I/O port
● Ratiometric conversion mode available eliminating errors due to on board switch resistances
