Single-Ended SD Video Filter Amplifier with Output Short-to-Battery Protection
The ADA4432-1 (single-ended output) is a fully integrated video reconstruction filters that combines overvoltage protection (short-to-battery [STB] protection) and short-to-ground (STG) protection on the outputs, with excellent video specifications and low power consumption. The combination of STB protection and robust ESD tolerance allows the ADA4432-1 to provide superior protection in the hostile automotive environment.
The ADA4432-1 is a single-ended input/single-ended output video filter capable of driving long back-terminated cables. The short-to-battery protection integrated into the ADA4432-1 protects against both dc and transient overvoltage events, caused by an accidental short to a battery voltage up to 18 V. The Analog Devices, Inc., short-to-battery protection eliminates the need for large output coupling capacitors and other complicated circuits used to protect standard video amplifiers, saving space and cost.
The ADA4432-1 features a high-order filter with −3 dB cutoff frequency response at 10 MHz and 45 dB of rejection at 27 MHz. The ADA4432-1 features an internally fixed gain of 2 V/V. This makes the ADA4432-1 ideal for SD video applications, including NTSC and PAL. The ADA4432-1 operate on single supplies as low as 2.6 V and as high as 3.6 V while providing the dynamic range required by the most demanding video systems.
The ADA4432-1 is offered in an 8-lead, 3 mm × 3 mm LFCSP package. The ADA4432-1 is also available in a 6-lead SOT-23 package. All are rated for operation over the wide automotive temperature range of −40°C to +125°C.

The ADA4432-1BRJ-EBZ evaluation board makes it easy for designers to quickly observe the performance of the ADA4432-1 video filter in a real-world application. Input signals are applied through the SMA jack (IN), and output signals are taken from the SMA jack (OUT). Power is applied through the red +VS test point. Ground the black GND test point. The ADA4432-1 operates on a single-supply voltage ranging from 2.7 V to 3.6 V and draws approximately 7 mA.
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.
