GENERAL DESCRIPTION
The ADA4432-1BCP-EBZ evaluation board makes it easy for
designers to quickly observe the performance of the ADA4432-1
video filter LFCSP package in a real-world application. The
ADA4432-1BCP-EBZ uses the same printed circuit board (PCB)
as the ADA4433-1BCP-EBZ,and it is marked as such; however,
its configuration is optimized for the ADA4432-1.
Input signals are applied through the SMA jack (+IN), and
output signals are taken from the SMA jack (+OUT). Power is
applied through the red +VS test point. Ground the black GND
test point. The ADA4432-1 operates on a single-supply voltage
ranging from 2.7 V to 3.6 V and draws approximately 7 mA.
The evaluation board is configured with an input termination
resistor (R1) of 75 Ω. Choose this resistor to provide the correct
termination or load for the input signal source. For example,
some video encoders use current mode video digital-to-analog
converter (DAC) outputs that require a 300 Ω load resistance.
In this case, replace R1 with a 300 Ω resistor.
The ADA4432-1BCP-EBZ evaluation board is configured to drive
a back terminated 150 Ω load. A series back-termination resistor
of 75 Ω is installed on the output at R7. If the input impedance
of the load is different from 75 Ω, then R7 can be changed to
match the actual load impedance.
The ADA4432-1 can be powered down (disabled) by grounding
the orange ENA test point at the top left of the evaluation board.
On the evaluation board, this pin is pulled up to +VS through
the 4.99 kΩ resistor (R3).
In normal operation, the short-to-battery output flag (STB) is held
at a logic low. During a short-to-battery fault condition (where
a voltage ranging from 5 V to 18 V is applied to either or both
outputs), the STB output voltage is driven to a logic high state.
The STB yellow test point (lower left side of the evaluation board)
can be used to monitor the short-to-battery output flag function.
Figure 1 and Figure 2 show the evaluation board primary side
and secondary side, respectively. Figure 3 shows the evaluation
board schematic. The PCB layout pattern for the primary side
and secondary side are shown in Figure 4 and Figure 5.
