EVM Basic Functions

common connector headers. Refer to the accompanying DSK manual for
proper orientation. If the TI DSK does not map out correctly with the EVM
’
s
common connector headers, then a smart adapter, SPRA711 adapter, can be
used. The smart adapter routes the necessary signals properly with ease by
correctly configuring the adapter board for the DSK being used.
A precision reference voltage is provided onboard, which can be adjusted to
the user
’
s preference through the R29 potentiometer. This sets the effective
range of the DAC
’
s output signal.
The output of the DAC can be monitored through three different access points
which are as follows: an SMA jack (J11), a test point (TP1), and also a header
through pin 1 of J3. The 6-pin header, W13, provides different flavors of the
DAC output, but requires the output op-amp, U12, to be configured correctly
first for the desired waveform characteristic. Shorting pins 1 and 2 of W13 may
allow the user to monitor the raw output of the DAC.
A bipolar mode of operation is integrated into the EVM board through the
output op-amp, U12. This option to operate in bipolar mode yields a rail-to-rail
output voltage range of
±
5 V maximum. Although the op-amp, U12, circuit is
originally intended for bipolar operation, a single supply option can also be
implemented by properly configuring the jumpers.
