Kits/Evaluation Systems
Configure the on-board buffers for a positive (noninverting)
gain by performing the following steps:
1) Cut open the trace at locations R31, R33, and R35.
2) Select a value of 10k Ω for resistors R32, R34, and
R36.
3) Calculate resistors R31, R33, and R35 using the
equations below.
4) Install R31, R33, and R35 in their respective locations:
Disconnect the buffers from the AFEs by cutting the
trace at locations R28, R29, and R30. Connect the low-
speed DAC loads to the DAC1, DAC2, and DAC3 pads
on the EV kit. If the load capacitance is between 5pF
and 15pF, cut the trace and install 10k Ω resistors at
locations R25, R26, and R27. Resistors are not required
if the load is less than 5pF.
Using an Alternative SPI Interface
The EV kits provide pads and jumpers that allow an
alternative SPI interface to be used. Connect the inter-

face to the CS , SCLK, DIN, DOUT, and OGND pads.
Ensure that the SPI voltages are compatible with all of
the AFE ’s working voltages. Refer to the individual

The low-speed buffers (U6) on the EV kits are optional and,
if desired, can be disconnected from the DAC outputs of
the AFEs.
