DESCRIPTION
The TSC2046 is a next-generation version to the ADS7846
4-wire touch screen controller which supports a low-voltage
I/O interface from 1.5V to 5.25V. The TSC2046 is 100% pin-
compatible with the existing ADS7846, and will drop into the
same socket. This allows for easy upgrade of current appli-
cations to the new version. The TSC2046 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 0V to 6V.
The low-power consumption of < 0.75mW typ at 2.7V (refer-
ence off), high-speed (up to 125kHz sample rate), and on-
chip drivers make the TSC2046 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 TSC2046 is available in
TSSOP-16, QFN-16, and VFBGA-48 packages and is speci-
fied over the –40°C to +85°C temperature range.
