Analog Devices introduces high-speed video amplifiers for automotive video
Analog Devices introduces a line of high-speed video amplifiers, the ADA4830-1/2 and ADA4432-1/33-1, that integrate battery short-circuit protection and fault detection for analog video systems in automotive safety and infotainment applications. Available in a 3mm x 3mm package, these new integrated video amplifiers from Analog Devices save at least 80% of board space compared to fully separate solutions, making them ideal for space-constrained applications such as rear-view cameras.
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 provide designers with complete chipsets for transmitting analog video signals over shielded and unshielded twisted pair cables. The above video amplifiers can also be used alone to provide receiver (ADA4830-1/2) and transmitter (ADA4432-1/33-1) functions as part of the video signal chain. All of these new amplifiers have built-in battery short-circuit protection up to 18 V, ground short-circuit protection, fault detection, a wide common-mode voltage range and robust ESD performance.
Curt Ventola, marketing and application engineering manager for ADI's high-speed signal conditioning group, said: "Whether running video from a rear-view camera or a rear-rear display, fault-tolerant video signal chains are prone to catastrophic failure, and troubleshooting and repair can be costly and time-consuming. ADI's new video amplifiers are well suited for harsh and demanding automotive applications and provide the necessary protection against DC and transient overvoltages, ESD and large common mode voltages."
