by delaying the conversion time or by adding an addi-
tional panel setup time (tPSU) using the panel setup tim-
ing configuration register (0x05). The advantage of
using a dedicated panel setup time is that the ADC
does not consume power during this interval. The
required panel setup time is a function of the panel
end-to-end resistance, the capacitance of the panel,
and any board-level components.
When using a measurement command with CONT = 1 in
a direct conversion mode, the devices remain in the
requested setup mode in preparation for the succeeding
measurement. The panel does not return to TDM/LPM
and the interrupt status is not modified as a result of a
measurement command with CONT = 1 issued. See
Figure 12.
Combined Commands
In direct conversion modes, the panel returns to a TDM
at the conclusion of a combined command and all data
are
tagged
accordingly.
The
MAX11800–
MAX11803 then idle in a low-power mode determined
by the interrupt mode selected. See Figure 13.
Auxiliary Measurement Command
The MAX11800–MAX11803 support measurement of an
auxiliary input using the internal ADC in direct conver-
sion mode only. When programmed, the devices sam-
ple and quantize the voltage at AUX using VDD as the
ADC reference. The MAX11800–MAX11803 store the
result in the same manner as X, Y, Z1, and Z2 measure-
ments, but do not add data tagging. The devices also
support averaging functions. Auxiliary measurements
do not require any panel setup procedure. There is no
