ADA4433-1BCPZ-R7

Overview

The ADA4433-1BCPZ-R7 is a fully differential SD video filter amplifier with integrated short-to-battery and short-to-ground protection. It operates on a single supply voltage ranging from 2.6 V to 3.6 V, drawing a typical quiescent current of 13.2 mA. The device features a fifth-order low-pass filter response with a -3 dB bandwidth of 9.9 MHz and provides 45 dB rejection at 27 MHz. It includes an enable pin that reduces power-down current to 13.5 µA. The component is housed in an 8-lead LFCSP package and supports operation across a temperature range of -40°C to +125°C.

Feature Summary

• Fully differential signal processing architecture for improved noise immunity
• Integrated output overvoltage protection up to 18 V with diagnostic flag
• Internal short-to-ground current limiting for robust fault tolerance
• Ultralow power consumption with dedicated disable mode

Applications

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

Procurement Notes

Verify the specific suffix R7 indicates reel packaging when sourcing. Confirm the BC subcode corresponds to the automotive qualified grade required for your environment. Ensure the LFCSP-8 footprint matches your PCB layout constraints. Cross-reference the datasheet revision F specifications against your system requirements before finalizing procurement.

Selection Notes

Select this component when differential video transmission is required to mitigate ground noise in harsh environments. The fixed gain of 2 V/V simplifies circuit design for standard definition video formats like NTSC and PAL. Consider the 13.5 µA shutdown current if battery life or standby power is a critical constraint for the application.

Part Context

This part belongs to the ADA4432-1/ADA4433-1 family of SD video filter amplifiers. While the ADA4432-1 offers single-ended output, the ADA4433-1 provides fully differential outputs. Both share identical protection features and filter characteristics but differ in input/output topology to suit different signal chain configurations.

Replacement Considerations

The ADA4432-1BCPZ-R7 is pin-compatible but provides single-ended output instead of differential. Verify that the receiving stage can accept single-ended signals if substituting.
