MAX19710–MAX19713 Evaluation
Kits/Evaluation Systems
Reference
The MAX19710–MAX19713 feature two reference oper-
ation modes. The EV kits can be configured to use
either the internal (1.024V) reference or an external
user-supplied reference applied at the REFIN pad. The
AFEs generate the REFP and REFN voltages from the
selected reference voltage (refer to the MAX19710,
MAX19711, MAX19712, and MAX19713 data sheets for
more details). Measure the REFP and REFN voltages at
TP1 and TP2, respectively. Jumper JU2 controls the ref-
erence mode. See Table 2 for jumper configurations.

SHUNT POSITION DESCRIPTION
Digital Data Headers
The MAX19710–MAX19713 EV kits feature two 10-bit
parallel data buses used for full-duplex operation. The two
data buses are accessed on the EV kit through header
connectors J2 (Rx ADC bus) and J3 (Tx DAC bus).
Digital Data Bit Locations
Driver U2 buffers the digital outputs of the Rx ADC. This
driver is able to drive large capacitive loads, which may
be present at the logic analyzer connection. The out-
puts of the buffer are connected to a 40-pin header
(J2). The 20-pin header (J3) is used to connect to the
digital input of the Tx DAC. See Table 3 for bit locations
on headers J2 and J3.

Internal reference mode.
External reference mode.
Apply an external reference voltage to
the REFIN pad.
Configuring the Low-Speed DAC Buffers
The MAX19710–MAX19713 EV kits feature on-board
configurable buffers. By default, these buffers are config-
ured for unity gain. Measure the buffered voltage at the
BDAC1, BDAC2, and BDAC3 pads. Measure the
unbuffered voltage at the DAC1, DAC2, and DAC3 pads.
