Detailed Description of Hardware

The MAX5134 EV kit provides a proven layout for the

MAX5134. An on-board analog output signal header

(H2), an on-board digital input/output signal header

(H3), and jumpers to disconnect the on-board micro-

controller are all included on the EV kit.

Reference

At power-up, the MAX5134 EV kit defaults to using the

internal 2.440V reference.

To use AVDD as the reference, place a shunt on jumper

JU9 in the 2-3 position. For off-board external refer-

ences, connect a user-supplied reference voltage to

REFIN and remove the shunt on jumper JU9. Type in

the reference voltage value in the Set Vref edit box and

press the Set Vref button. The MAX5134 EV kit soft-

ware uses the value in the Set Vref edit box to calcu-

late the input and output register voltage values and

does not affect any commands to the part.
