ADA4432-1WBCPZ-R7

Overview

The ADA4432-1WBCPZ-R7 is an automotive-grade, single-ended SD video filter amplifier with integrated short-to-battery protection. It features a fifth-order low-pass filter with a -3 dB bandwidth of 10.5 MHz and 45 dB rejection at 27 MHz. The device operates on a single supply voltage ranging from 2.6 V to 3.6 V, drawing a typical quiescent current of 7.6 mA. It includes output overvoltage protection up to 18 V and a short-to-battery flag for diagnostics.

Feature Summary

• Integrated short-to-battery protection up to 18 V with diagnostic flag output
• Fifth-order low-pass video filter optimized for SD applications
• Low power consumption with ultralow power-down current
• AEC-Q100 qualified for harsh automotive environments

Applications

• Automotive rearview cameras
• Automotive video electronic control units (ECUs)
• Surveillance video systems

Procurement Notes

Verify the specific 'W' suffix against official documentation to confirm extended temperature range compliance (-40°C to +125°C). Ensure the LFCSP package dimensions match the design footprint. Confirm RoHS3 status and moisture sensitivity level prior to assembly.

Selection Notes

Select this component for single-ended video signal processing requiring robust fault protection. It is suitable for driving long back-terminated cables in automotive settings. Consider the ADA4433-1 if differential output is required instead of single-ended.

Part Context

This part belongs to the ADA4432/ADA4433 family of SD video filter amplifiers. It is designed specifically for automotive applications where reliability under electrical stress is critical. The device integrates filtering and protection functions typically requiring multiple discrete components.

Replacement Considerations

The ADA4432-1BCPZ-R7 is a pin-compatible alternative within the same family but may lack the specific 'W' suffix characteristics regarding temperature range or performance variations defined by Analog Devices.
