ADA4432-1BCPZ-R7

Overview

The ADA4432-1BCPZ-R7 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 10 MHz bandwidth
• Low power-down current of 13.5 µA

Applications

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

Procurement Notes

Verify the specific suffix R7 indicates reel packaging when sourcing. Confirm AEC-Q100 automotive qualification status for your target environment. Check datasheet Rev F for updated performance characteristics. Ensure compatibility with 8-lead LFCSP footprints during PCB design.

Selection Notes

Select this component for applications requiring robust output protection against battery shorts. Consider the single-ended output configuration versus the differential ADA4433-1 based on system topology. Evaluate the 10 MHz bandwidth against signal requirements. Verify thermal dissipation limits within the LFCSP package.

Part Context

This part belongs to the ADA4432/ADA4433 series of SD video filter amplifiers. It is designed specifically for harsh automotive environments where standard video amplifiers might fail due to electrical stress. The series integrates reconstruction filtering with protection circuitry to simplify system design.

Replacement Considerations

The pin-compatible ADA4433-1 offers a fully differential output instead of single-ended. Both share identical protection features and filter characteristics.
