ACPM-7891 PA Control Board

We have designed the

ACPM-7891 PA control board to

interface with the LTC1758

demo board to simplify engineer-

ing efforts. Test Setup I, Figure 6,

illustrates the equipment setup if

the LTC1758 demo board is to be

used with the ACPM-7891 PA

Control Board.

However, the ACPM-7891 PA

Control Board can also be tested

without using the LTC1758 demo

board. Test Setup II, Figure 7,

illustrates the equipment setup

under that scenario.
