ADA4433-1BCPZ-R2

Overview

The ADA4433-1BCPZ-R2 is a fully differential SD video filter amplifier from Analog Devices, designed for automotive and surveillance applications. It integrates fifth-order low-pass filtering with short-to-battery protection up to 18 V and short-to-ground protection. The device operates on a single supply voltage ranging from 2.6 V to 3.6 V. Key electrical specifications include a typical quiescent current of 13.2 mA, a -3 dB bandwidth of approximately 9.9 MHz, and an internal fixed gain of 2 V/V (6 dB). It features an ultralow power-down current of 13.5 µA when disabled via the ENA pin.

Feature Summary

• Integrates fully differential video reconstruction filtering with built-in output overvoltage and short-to-ground protection circuits.
• Provides a dedicated short-to-battery output flag (STB) for wire diagnostics and fault indication.
• Supports flexible input configurations, functioning as a fully differential input-to-output or single-ended input-to-differential output driver.
• Features an enable/disable control pin that reduces supply current to ultralow levels during inactive states.

Applications

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

Procurement Notes

Verify the specific suffix 'R2' against official documentation to confirm reel packaging details, as datasheets may reference 'R7'. Confirm AEC-Q100 qualification status for automotive deployment. Ensure PCB layout adheres to high-speed design practices due to the LFCSP package and signal integrity requirements.

Selection Notes

Select this component for applications requiring robust protection against battery shorts in harsh environments. It is suitable for driving twisted pair or coaxial cables with minimal attenuation. Consider the ADA4432-1 if a single-ended output configuration is preferred instead of the differential output provided by this model.

Part Context

This part belongs to the ADA4432-1/ADA4433-1 series of SD video filter amplifiers. The series is characterized by its ability to combine filtering, buffering, and protection in a single small package. It is specifically optimized for low-voltage, low-power operation within the automotive sector.

Replacement Considerations

The ADA4432-1 is a pin-compatible alternative offering single-ended output instead of differential. Verify functional equivalence regarding protection thresholds and filter characteristics before substitution.
