ADA4432-1BCPZ-R2

Overview

The ADA4432-1BCPZ-R2 is a single-channel SD video filter amplifier from Analog Devices, housed in an 8-lead LFCSP package. It operates on a supply voltage range of 2.6 V to 3.6 V with a typical quiescent current of 7.6 mA. The device features a fifth-order low-pass filter with a -3 dB bandwidth of 10.5 MHz and provides a fixed passband gain of 6 dB. It includes integrated short-to-battery protection up to 18 V and short-to-ground protection.

Feature Summary

• Integrated overvoltage (short-to-battery) protection up to 18 V
• Short-to-battery output flag for wire diagnostics
• Fifth-order low-pass video filter with 0.1 dB flatness to 3 MHz
• Low power-down current of 13.5 µA typical

Applications

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

Procurement Notes

Verify the specific suffix R2 against official documentation to confirm reel packaging specifications. Ensure compatibility with AEC-Q100 automotive qualification requirements if deploying in vehicle environments. Cross-reference pin configurations and thermal resistance data with the manufacturer datasheet prior to integration.

Selection Notes

Select this component for applications requiring robust output protection against battery shorts and ground faults. The single-ended output configuration suits direct interfacing with standard video receivers. Evaluate the 10.5 MHz bandwidth against target signal frequencies to ensure adequate out-of-band rejection at 27 MHz.

Part Context

This part belongs to the ADA4432-1/ADA4433-1 family of fully integrated video reconstruction filters. It combines high-performance filtering with extensive protection circuitry designed specifically for hostile automotive environments. The series supports both AC and DC coupling methods for flexible system design.
