- Integrated battery short-circuit protection (up to 18V), ground short-circuit protection, fault detection, wide common-mode voltage range, and robust electrostatic discharge (ESD) protection.
- Occupies over 80% less board space compared to fully discrete solutions, making it suitable for space-constrained applications such as automotive rearview cameras.

June 12, 2012 – Analog Devices ( www.analog.com , NASDAQ: ADI), a leader in the high-performance semiconductor market for signal processing applications, today introduced a series of high-speed video amplifiers with integrated battery short-circuit protection and fault detection circuitry for analog video systems in automotive safety and infotainment applications. Available in a 3mm x 3mm package, ADI’s new integrated video amplifiers take up more than 80% less board space compared to fully discrete solutions and are suitable for space-constrained applications such as rear cameras. By utilizing the ADA4830-1 (single-channel) and ADA4830-2 (dual-channel) video differential amplifiers and the ADA4432-1 (single-ended output) and ADA4433-1 (differential output) analog video filter amplifiers, designers obtain a complete chipset capable of transmitting analog video signals over shielded and unshielded twisted cables. In addition, these video amplifiers can be used individually to provide receiver (ADA4830-1/2) and transmitter (ADA4432-1/33-1) functions as part of a video signal chain. All of the newly introduced amplifier products feature battery short-circuit protection (up to 18V), ground short-circuit protection, fault detection, a wide common-mode voltage range, and robust ESD protection.

Curt Ventola, Marketing and Application Engineering Manager at Analog Devices’ High-Speed Signal Conditioning Group, pointed out, “Whether connecting video from a rear camera or transmitting it to a rear-seat display, a video signal chain lacking sufficient fault tolerance can be vulnerable to serious errors. Furthermore, this can result in significant costs and time spent on troubleshooting and recovery.” He explained, “ADI’s new video amplifier is suitable for harsh and demanding automotive applications, providing essential protection against DC, as well as transient overvoltage, ESD, and large common-mode voltage in these areas.”

Additional Information on ADA4830-1/-2 Video Differential Amplifier
The ADA4830-1 and ADA4830-2 high-speed video differential amplifiers are designed for use as Composite Video Blanking and Synchronous (CVBS) signal receivers in Standard-Definition (SD) PAL/NTSC video applications. These new differential amplifiers not only incorporate battery short-circuit (input) protection (up to 18V) on a single 3–5V power supply but also support a battery short-circuit flag to indicate a fault condition at the input. Additionally, the ADA4830-1 and ADA4830-2 support excellent ESD tolerance up to +8kV Human Body Model (HBM), a wide input common-mode voltage range extending to -8.5V below ground, and a 55dB common-mode cutoff (7MHz).

Additional Information on ADA4432-1 and ADA4433-1 Analog Video Filter Amplifiers
The ADA4432-1 (single-ended output) and ADA4433-1 (differential output) analog video filter amplifiers are designed as transmitters for automotive analog video filtering applications. These amplifiers feature the same 18V battery short-circuit protection (output), fault flag, and +8kV HBM tolerance as the ADA4830. Additionally, ADI's new video filter amplifiers feature continuous output ground short-circuit protection and excellent video specifications. The ADA4432-1 and ADA4433-1 include high-order video filters with a -3dB cutoff frequency (10MHz) and a 45dB cutoff (27MHz) performance.
