SS7646
8/21/2004 Rev.2.01
Reference Input
The voltage difference between +REF and –REF
(shown VREF in Figure 5), in the range of 1V to + VDD,
sets the Analog-to-Digital converter (ADC) input
range. The full-scale analog input range of
the
SS7646 is therefore from 0 to V REF.
Typically the reference input is an external precise
voltage source VREF (MODE0=1, see Table IV) for
touch screen and auxiliary inputs measurement.
Figure 6 shows the configuration for a Y coordinate
measurement with MODE0=1. When utilizing the
panel measurement, the VREF must equal VDD as input
range is from 0 to VDD. If the reference input is from
the power supply directly, as Figure 12 shows for
example, special care must be taken to avoid noise
from the power supply.
When making touch screen measurements only, the
reference input can be set from VDD directly
(MODE0=0) and discard the VREF input. Figure 7
shows the configuration for a Y coordinate
measurement with MODE0=0.
Examples of DIN Configuration
Table VI shows DIN configurations for specified
applications.
