Analog Devices’ Video Amplifiers Integrate Short-to-Battery Protection and Fault Detection for Automotive Video Applications

Analog Devices, Inc. (ADI), a global leader in high-performance
signal processing technology, today 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 new integrated video amplifiers reduce board
space by at least 80 percent compared to fully discrete solutions
and are ideal for space-constrained applications, such as rear-view
cameras. 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.

“Whether you’re running video from a rear-view camera or to a
rear-seat display, a video signal chain without adequate fault
tolerance is vulnerable to catastrophic failure. That can result in
costly and time consuming troubleshooting and repairs,” said Curt
Ventola, marketing and applications engineering manager, High-Speed
Signal Conditioning group, Analog Devices. “ADI’s new video
amplifiers are fully qualified for harsh, demanding automotive
applications, where they provide the necessary protection against
DC and transient over-voltage, ESD and large common-mode
voltages.”
More About the ADA4830-1/-2 Video Difference
AmplifiersThe ADA4830-1 and ADA4830-2 high-speed video
difference amplifiers are designed for use as receivers of CVBS
(Composite Video Blanking and Synchronous) signals in
standard-definition PAL/NTSC video applications. In addition to
integrated short-to-battery (input) protection up to 18 V on a
single 3-V to 5-V supply, the new difference amplifiers include a
short-to-battery flag that indicates the presence of a fault
condition at the input. The ADA4830-1 and ADA4830-2 also have
excellent ESD tolerance to up ±8-kV Human Body Model (HBM), a wide
input common-mode voltage range that extends to -8.5 V below ground
and 55-dB common mode rejection at 7-MHz.
More About the ADA4432-1 and ADA4433-1 Analog Video Filter
AmplifiersThe ADA4432-1 (single-ended output) and the ADA4433-1
(differential output) analog video filter amplifiers are designed
as transmitters for automotive analog video filtering applications.
They feature the same 18-V short-to-battery protection (output),
fault flags and ±8-kV HBM tolerance as the ADA4830. Additionally,
ADI’s new video filter amplifiers feature continuous output
short-to-ground protection and excellent video specifications. The
ADA4432-1 and ADA4433-1 include a high-order video filter with a
-3dB cutoff frequency at 10 MHz and 45-dB of rejection at 27
MHz.
