GENERAL DESCRIPTION
The ADA4830-1 is a monolithic high speed difference amplifier
that integrates input overvoltage (short to battery) protection of
up to 18 V with a wide input common-mode voltage range and
excellent ESD robustness. The ADA4830-1 is intended for use
as a receiver 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 combines the high speed and the precision that
allow 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 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 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 can withstand direct short to
battery voltages as high as 18 V on its input pins.
The ADA4830-1 is designed to operate at supply voltages as low
as 2.9 V and as high as 5.5 V, using only 6.8 mA of supply
current per channel. The device provides true single-supply
capability, allowing the input signal to extend 8.5 V below the
negative rail and to 8.5 V above ground on a single 5 V supply.
At the output, the amplifier can swing to within 250 mV of
either supply rail into a 150 Ω load.
The ADA4830-1 presents a gain of 0.5 V/V at its output. This is
designed to keep the video signal within the allowed range of
the video decoder, which is typically 1 V p-p or less.
The ADA4830-1 is available in a 3 mm × 3 mm, 8-lead LFCSP
package and is specified for operation over the automotive
temperature range of 40°C to +125°C.
