10 / 22 page TSC2003 10 SBAS162D www.ti.com INTERNAL REFERENCE The TSC2003 has an internal 2.5V voltage reference that can be turned ON or OFF with the power-down control bits, PD0 and PD1 (see Table II and Figure 3). The internal reference is powered down when power is first applied to the device. The internal reference voltage is only used in the single-ended reference mode for battery monitoring, tem- perature measurement, and for measuring the auxiliary in- put. Optimal touch screen performance is achieved when using a ratiometric conversion; thus, all touch screen mea- surements are done automatically in the differential mode.
