DESCRIPTION

The TSC2046E is the next-generation version of the ADS7846 4-wire touch screen controller, supporting a

low-voltage I/O interface from 1.5 V to 5.25 V. 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 2.5-V 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 2.7 V, while monitoring the battery

voltage from 0 V to 6 V.

The low power consumption of less than 0.75 mW (typ) at 2.7 V (reference off), high-speed (up to 125-kHz

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 a TSSOP-16 package and is specified over the -40°C to +125°C

temperature range.
