ADA4433-1WBCPZ-R2

Overview

The ADA4433-1WBCPZ-R2 is a fully differential SD video filter amplifier with integrated short-to-battery and short-to-ground protection. It operates on a single supply from 2.6 V to 3.6 V, drawing 13.2 mA typical quiescent current. The device features a fifth-order low-pass filter with a -3 dB bandwidth of 9.9 MHz, 0.1 dB flatness to 3 MHz, and 45 dB rejection at 27 MHz. It provides an internally fixed gain of 6 dB (2 V/V) and includes an STB output flag for wire diagnostics. The component is housed in an 8-lead LFCSP package and supports operation from -40°C to +125°C.

Feature Summary

• Integrated overvoltage protection withstands up to 18 V on outputs without damage.
• Built-in short-to-battery indicator flag enables real-time wire diagnostics.
• Fully differential architecture reduces ground noise effects in signal chains.
• Ultralow power-down mode reduces current consumption to 13.5 µA.

Applications

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

Procurement Notes

Verify the specific suffix 'R2' against official Analog Devices documentation to confirm reel packaging specifications. Ensure compatibility with AEC-Q100 automotive qualification requirements if deploying in vehicle environments. Cross-reference the datasheet revision F for updated thermal resistance and performance characteristics before finalizing procurement orders.

Selection Notes

Select this component when differential signal processing is required alongside robust fault protection. It serves as a direct replacement for standard video amplifiers by eliminating external coupling capacitors. Verify that the system requires a fixed 2 V/V gain and fits within the 2.6 V to 3.6 V supply voltage constraints.

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 variant provides fully differential outputs. Both share identical protection mechanisms and filter characteristics but differ in input/output topology to suit various transmission line configurations.

Replacement Considerations

The ADA4432-1 is pin-compatible but provides single-ended output instead of differential. Standard video amplifiers lacking integrated short-to-battery protection require additional external circuitry for equivalent fault tolerance.
