The ADS7846 is 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 batteryvoltage from 0V to 6V.FEATURES: – SAME PINOUT AS ADS7843 – 2.2V TO 5.25V OPERATION – INTERNAL 2.5V REFERENCE – DIRECT BATTERY MEASUREMENT (0V to 6V) – ON-CHIP TEMPERATURE MEASUREMENT – TOUCH-PRESSURE MEASUREMENT – QSPITM/SPITM 3-WIRE INTERFACE – AUTO POWER-DOWN – TSSOP-16 PACKAGESAPPLICATIONS: – PERSONAL DIGITAL ASSISTANTS – PORTABLE INSTRUMENTS – POINT-OF-SALE TERMINALS – PAGERS – TOUCH SCREEN MONITORS – CELLULAR PHONES
