DESCRIPTION
The TSC2046E is the next-generation version of the
ADS7846 4-wire touch screen controller, supporting a
low-voltage I/O interface from 1.5V to 5.25V. The
TSC2046E is 100% pin-compatible with the existing
ADS7846, and drops into the same socket. This design
allows for an easy upgrade of current applications to the
new version. The TSC2046E 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
a supply voltage of 2.7V, 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 sample rate),
and on-chip drivers make the TSC2046E 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
TSC2046E is available in TSSOP-16, QFN-16, and
VFBGA-48 packages and is specified over the –40°C to
+85°C temperature range.
