ADA4830-2

High Speed Difference Amplifier with Input Short-to-Battery Protection
Manufactured by:

Product Details

The ADA4830-1(single) and the 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 the high speed and 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 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 ADA4830-1and 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 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 ADA4830-1 and ADA4830-2 presents a gain of 0.5 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 ADA4830-1 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.
