Surveillance systems GENERAL DESCRIPTION
The ADA4830-1 (single) and ADA4830-2 (dual) are monolithic,
high speed difference amplifiers that integrate input overvoltage
(short-to-battery) protection of up to 18 V with a wide input
common-mode voltage range and excellent ESD robustness.
They are intended for use as receivers for differential or pseudo
differential CVBS and other high speed video signals in harsh,
noisy environments such as automotive infotainment and vision
systems. The ADA4830-1 and ADA4830-2 combine high speed
and precision, which allows for accurate reproduction of CVBS
video signals, yet rejects unwanted common-mode error voltages.
The short-to-battery protection that is integrated into the
ADA4830-1 and ADA4830-2 employs fast switching circuitry to
clamp and hold internal voltage nodes at a safe level when an input
overvoltage condition is detected. This protection allows the inputs
of the ADA4830-1 and ADA4830-2 to be directly connected to a
remote video source, such as a rearview camera, without the
need for large expensive series capacitors. The ADA4830-1 and
ADA4830-2 can withstand direct short-to-battery voltages as
high as 18 V on their input pins. …
