3.1.1 DAC Pull-up Voltage: Motherboard
The TSC100PM motherboard can supply either +5V or +3.3V to the daughter card for use
as the pull-up voltage for the TSC2200's digital-to-analog converter (DAC). This selection
is made on the TSC100PM through JMP1.
3.1.2 DAC Pull-up Voltage: Daughter card
The TSC2200EVM daughter card has provisions for two different DAC pull-up circuits.
The first circuit is R3 and R5, which are to be user-installed and connected to a pull-up
voltage connected to the V+ input at J4 on the TSC2200EVM daughter card. The voltage
V+ must be less than or equal to the supply voltage for the TSC2200, which is nominally
+3.3V. This circuit is chosen by connecting positions 1 and 2 on JMP1 of the daughter
card.
The on-board resistors, R4 and R6, are connected to the DAC voltage provided by the
motherboard. Since the motherboard can supply a voltage higher than the supply voltage
of the TSC2200, Q1 is used to protect the TSC2200. This circuit is chosen by connecting
positions 2 and 3 on JMP1 of the daughter card.
3.1.3 VDAC Output Selection
JMP2 on the daughter card selects which resistor network connected to the DAC will be
connected to the VDAC output on connector J4. Positions 1 and 2 connected will select
the user-supplied R3/R5 resistor array, while positions 2 and 3 connected together select
the on-board resistor network of R4/R6.
3.2 I/O Connectors and Signals
The various connectors on the TSC2200EVM are described in this section.
