ADA4433-1WBCPZ-R7

Overview

The ADA4433-1WBCPZ-R7 is a fully differential SD video filter amplifier with integrated short-to-battery and short-to-ground protection. It features a fifth-order low-pass filter with a -3 dB bandwidth of 9.9 MHz, 0.1 dB flatness to 3 MHz, and 45 dB rejection at 27 MHz. Operating on a single supply from 2.6 V to 3.6 V, it draws 13.2 mA typical quiescent current and reduces to 13.5 µA in power-down mode. The device includes an STB output flag for diagnostics and operates within the -40°C to +125°C automotive temperature range.

Feature Summary

• Fully differential video reconstruction filter with fixed gain
• Integrated short-to-battery protection up to 18 V
• Short-to-battery diagnostic output flag
• Ultralow power-down current consumption

Applications

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

Procurement Notes

Verify the specific suffix 'W' indicates wide temperature rating compliance during procurement. Confirm package type matches LFCSP-8 requirements. Ensure ESD handling protocols are followed due to sensitivity. Cross-reference datasheet Rev F specifications against ordering documentation to confirm parameter alignment.

Selection Notes

Select this component for applications requiring robust overvoltage protection in harsh environments. The differential architecture minimizes ground noise effects compared to single-ended alternatives. Consider the fixed gain and filter characteristics when designing signal chains for standard definition video formats like NTSC and PAL.

Part Context

This part belongs to the ADA4432-1/ADA4433-1 family of SD video filter amplifiers. The ADA4433-1 variant specifically provides fully differential outputs, distinguishing it from the single-ended ADA4432-1. Both share identical protection features and filter performance profiles within the same automotive-grade qualification framework.

Replacement Considerations

The ADA4432-1 serves as a pin-compatible alternative for single-ended output requirements. Verify interface compatibility if substituting between single-ended and differential configurations.
