Analog Devices Inc. (ADI) introduced a series of high-speed video amplifiers that integrate short-to-battery protection and fault detection for analog video systems in automotive safety and infotainment applications.

Housed in 3mm x 3mm packages, ADI’s integrated video amplifiers reduce board space by at least 80 percent compared to fully discrete solutions and are well-suited for space-constrained applications, such as rear-view cameras, according to ADI.

The ADA4830-1 (single-channel) and ADA4830-2 (dual-channel) video difference amplifiers, and ADA4432-1 (single-ended output) and ADA4433-1 (differential output) analog video filter amplifiers, provide designers with a complete chipset for transporting analog video signals over shielded and unshielded twisted pair cables. The video amplifiers also can be used independently to provide receiver (ADA4830-1/2) and transmitter (ADA4432-1/33-1) functions as part of a video signal chain. All of these new amplifiers feature integrated short-to-battery protection up to 18 V, short-to-ground protection, fault detection, wide common-mode voltage ranges and robust ESD (electro-static discharge) performance.
