MAX7440 Evaluation Kit
General Description
The MAX7440 evaluation kit (EV kit) is a fully assembled
and tested surface-mount board. The MAX7440 EV kit
includes the MAX7440, a six-channel reconstruction fil-
ter, unity-gain input-level-shift circuits, and output
buffers with a gain of 2V/V. The input and output buffers
are included to ease the evaluation of the MAX7440,
and are not needed in the actual application.
The MAX7440 EV kit can be also used to evaluate the
MAX7441 and MAX7442.

The MAX7440 EV kit is a fully assembled and tested
surface-mount board. Utilize the following steps to veri-
fy the board operation.
Do not turn on the power sup-
ply until all connections are completed.
Evaluating Channel 1 with a Ground-
Referenced Video Generator
1) Verify that there are shunts across on JU1 (pins 1
and 2), JU2 pins (1 and 2), and JU3 pins (1 and 2).
2) Verify that there are shunts across jumpers JU19
and JU31.
