Product Overview

The ADS7846N is a 4-wire Touch Screen Controller, 100% pin-compatible with the existing ADS7843 and drops into the same socket. This allows for easy upgrade of current applications to the new version. Only software changes are required to take advantage of the added features of direct battery measurement, temperature measurement and touch-pressure measurement. The ADS7846 also has an on-chip 2.5V reference that can be used for the auxiliary input, battery monitor and temperature measurement modes. The reference can also be powered down when not used to conserve power. The internal reference operates down to 2.7V supply voltage while monitoring the battery voltage from 0 to 6V. The low-power consumption of <0.75mW typical at 2.7V (reference off), high speed (up to 125kHz clock rate) and on-chip drivers make the controller an ideal choice.
  • On-chip temperature measurement
  • Touch-pressure measurement
  • Auto power-down
  • Green product and no Sb/Br
