MAX9700B Evaluation Kit
Jumper JU3 provides an option to select between a
differential or single-ended input mode for the EV kit.
See Table 5 for shunt positions.
Table 5. JU3 Jumper Selection
The MAX9700B EV kit can evaluate the MAX9700A,
MAX9700C, MAX9700D, and the MAX9712. To evalu-
ate a different IC, replace U1 with the desired part.
Refer to the MAX9700 or the MAX9712 data sheets for
additional information.
