Note 1: Connect LOAD to +5V (internal 400Ω loads on at all outputs).
Note 2: Program any one input to connect to any one output. See Table 1 or 2 for programming codes.
Note 3: Turn on the buffer at the selected output (Table 1 or 2).
Note 4: Drive the selected input with V
IN
, and measure V
OUT
at the -3dB frequency at the selected output.
Note 5: Program each numbered input to connect to the same numbered output (IN0 to OUT0, IN1 to OUT1, etc., for the MAX4456;
also IN4 to OUT0, IN5 to OUT1, etc., for the MAX4360.) See Table 1 or 2 for programming codes.
Note 6: Turn off all output buffers (Table 1 or 2).
Note 7: Drive all inputs with V
IN
, and measure V
OUT
at any output.
Note 8: Isolation (in dB) = 20log
10
(V
OUT
/V
IN
).
Note 9: Turn on all output buffers (Table 1 or 2).
Note 10: Drive any one input with V
IN
, and measure V
OUT
at any undriven output.
Note 11: Crosstalk (in dB) = 20log
10
(V
OUT
/V
IN
).
Note 12: Drive all but one input with V
IN
, and measure V
OUT
at the undriven output.
