DESCRIPTION

The TSC2046S 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 TSC2046S is 100% pin compatible with the existing ADS7846, and will drop into the same

socket. This allows for easy upgrade of current applications to the new version. The TSC2046S 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 (reference off), high-speed (up to 125kHz sample rate), and on chip

drivers make the TSC2046S 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 TSC2046S is available in TSSOP-16, QFN-16, and

VFBGA-48 packages and is specified over the –40°C to +85°C temperature range.
