GENERAL DESCRIPTION

GND1

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.

below ground 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 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.

The ADA4830-1 and ADA4830-2 present a gain of 0.50 V/V at their

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 ADA4830-1W and ADA4830-2W are automotive grade

version, qualified for automotive applications. See the

Automotive Products section for more details.

The ADA4830-1 and ADA4830-2 are 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. These devices provide true single-

supply capability, allowing the input signal to extend 8.5 V

The ADA4830-1 and ADA4830-2 are available in 3 mm × 3 mm

LFCSP packages, 8-lead and 16-lead, respectively, and are specified

for operation over the automotive temperature range of −40°C

to +125°C.
