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.
