ADA4432-1WBRJZ-R7

Overview

The ADA4432-1WBRJZ-R7 is a single-ended SD video filter amplifier with integrated short-to-battery protection. It features a fifth-order low-pass filter with a -3 dB bandwidth of 10 MHz and 45 dB rejection at 27 MHz. The device operates on a single supply voltage ranging from 2.6 V to 3.6 V, drawing a typical quiescent current of 7.6 mA. It includes an output flag for wire diagnostics and supports operation across a temperature range of -40°C to +125°C.

Feature Summary

• Integrated overvoltage protection up to 18 V and short-to-ground protection
• Fifth-order low-pass video filter with fixed gain of 2 V/V
• Short-to-battery output flag for system diagnostics
• 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 WBRJZ against official documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with automotive grade requirements and operating temperature ranges before integration into final designs.

Selection Notes

Select this component for applications requiring robust output protection against battery shorts in harsh environments. Consider the single-ended output configuration and fixed gain when designing signal chains for standard definition video transmission lines.

Part Context

This part belongs to the ADA4432/ADA4433 family of SD video filter amplifiers designed for automotive use. It complements the differential ADA4433-1 variant, offering a single-ended solution with identical protection features and filtering characteristics within the same package footprint options.

Replacement Considerations

The pin-compatible ADA4433-1 offers a fully differential output alternative. Verify input/output signal requirements to determine if single-ended or differential processing is necessary for the specific application.
