PIN-COMPATIBLE ADA4432-1 AND ADA4433-1
The ADA4432-1 and ADA4433-1 are single-ended output and
differential output, respectively, short-to-battery protected video
filters for automotive applications. Each version shares a common
package, the 8-lead LFSCP, which allows them to share a common
pinout and footprint. This allows a designer to change from a
single-ended output configuration to a differential output on
the same PCB with only minimal change to the external resistor
values and placements. Figure 48 and Figure 50 show the pin
configuration of the ADA4432-1 and ADA4433-1 in 8-lead
LFCSP packages. Figure 49 and Figure 51 show an example
schematic configured for the ADA4432-1 and the ADA4433-1,
respectively.
Example Configuration for Package-Compatible PCB
The single-ended output with the ADA4432-1 includes the following:
R1 matches the requirement for the source.
R2, R3, and R6 are not installed.
C3 is not installed.
R5 is chosen to match the receiver termination impedance.
R8 is 0 to provide ground reference.
The differential output with the ADA4433-1 includes the following:
R1 matches the requirement for the source.
R2 and R3 are chosen to provide the correct bias for IN.
C3 is for the IN bypass.
R5 and R6 are chosen to match the receiver termination
impedance.
R8 is not installed.
