MAX9586 Evaluation Kit
General Description
The MAX9586 evaluation kit (EV kit) is an assembled
and tested PCB that demonstrates the MAX9586 low-
power, single-channel video filter amplifier with AC-
coupled input buffer. The EV kit operates from 2.7V to
3.6V with a fixed gain of 2V/V.

Procedure
The MAX9586 EV kit is fully assembled and tested.
Follow the steps below to verify board operation.
Caution: Do not turn on the power supply until all
connections are completed.
1) Verify that a shunt is installed on jumper JU1,
pins 1-2.
2) Connect the power supply to the pads labeled
VDD and GND on the MAX9586 EV kit.
3) Connect the desired test signal from the video
signal generator to the INPUT BNC connector.
4) Connect the output signal from the OUTPUT BNC
connector to the input of the video measurement
equipment.
5) Turn on the power supply and verify the output
signal.

MAX9586 Evaluation Kit
Evaluates: MAX9586
Detailed Description
The MAX9586 EV kit demonstrates the MAX9586 low-
power, single-channel video filter amplifier with AC-
coupled input buffer. The EV kit operates from 2.7V to
3.6V with a fixed gain of 2V/V.
The MAX9586 has ±1dB (typ) passband flatness
of 7MHz and 62dB attenuation at 27MHz. The
output can be DC-coupled to a load of 75Ω, which is
the equivalent of two video loads, or AC-coupled to a
load of 150Ω.

AC-Coupling the Output
The outputs of the MAX9586 can be AC-coupled. To
keep the highpass formed by the 150Ω equivalent
resistance of the video transmission line to a corner
frequency of 4.8Hz or lower, remove the 0Ω resistor on
R3 and install a
≥
220µF capacitor on the C4 pad.
Jumper Selection
The MAX9586 EV kit incorporates a jumper (JU1) to
control the
SHDN
pin. See Table 1 for JU1 functions.
