產品總覽

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
