DESCRIPTION
The ADS7846 is a next-generation version to the industry
standard ADS7843 4-wire touch screen controller. 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 fea-
tures of direct battery measurement, temperature measure-
ment, 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 measure-
ment 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 0V to 6V.
The low-power consumption of < 0.75mW (typ at 2.7V,
reference off), high speed (up to 125kHz clock rate), and on-
chip drivers make the ADS7846 an ideal choice for battery-
operated systems such as personal digital assistants (PDAs)
with resistive touch screens, pagers, cellular phones, and
other portable equipment. The ADS7846 is available in the
small TSSOP-16, SSOP-16, QFN-16, and VFBGA-48 pack-
ages and is specified over the 鈥?0掳C to +85掳C temperature
range.
