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 Ω 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.
