Video amps for auto apps are highly integrated

Suited for analog video systems in automotive safety and infotainment applications, 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. 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 — all in 3 x 3-mm packages, further reducing board space by at least 80% compared to fully discrete solutions.

The amps 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. The ADA4830-1/2 also features an ESD tolerance to up ±8-kV HBM, a supply voltage of 2.9 to 5 V, a wide input common-mode voltage range that extends to –8.5 V below ground and 55-dB common mode rejection at 7-MHz. The ADA4432-1/33-1 include a high-order video filter with a –3-dB cutoff frequency at 10 MHz and 45-dB of rejection at 27 MHz and a supply voltage from 2.6 to 3.6 V.
