TSC2200IPWRG4

Overview

The TSC2200IPWRG4 is a programmable resistive touch screen controller manufactured by Texas Instruments. It integrates a 12-bit, 125 kS/s analog-to-digital converter (ADC) and supports 4-wire touch screen interfaces with keypad input capabilities. The device operates within a supply voltage range of 2.7 V to 3.6 V and draws 2.5 mA during active operation. Designed for surface-mount installation, it is housed in a VQFN-32 package. The component functions as a data converter IC suitable for applications requiring precise touch coordinate acquisition and key detection.
