Data Format
The TSC2300 output data is in straight binary format as shown in Figure 48. This figure shows the ideal output code
for the given input voltage and does not include the effects of offset, gain, or noise.

Reference
The TSC2300 has an internal voltage reference that can be set to 1.2 V or 2.5 V, through the reference control
register. This reference can also be set to automatically power down between conversions to save power, or remain on
to reduce settling time.
The internal reference voltage is only used in the single-ended mode for battery monitoring, temperature measurement,
and for utilizing the auxiliary inputs. Optimal touch screen performance is achieved when using a ratiometric
conversion, thus all touch screen measurements are done automatically in the differential mode.
An external reference can also be applied to the VREFIN pin, and the internal reference can be turned off.
