The ADA4433-1 is a fully integrated video reconstruction filters that combine overvoltage protection (short-to-battery [STB] protection) and short-to-ground protection [STG] on the outputs, with excellent video specifications and low power consumption. The combination of STB protection and robust ESD tolerance allows the ADA4433-1 to provide superior protection in the hostile automotive environment.
The ADA4433-1 is a fully differential video filter that can be used as a differential input to differential output or a single-ended input to differential output. It is capable of driving twisted pair or coaxial cable with minimal line attenuation. Differential signal processing reduces the effects of ground noise that can plague ground referenced systems. The ADA4433-1 is ideal for differential signal processing (gain and filtering) throughout the signal chain, easily simplifying the conversion between single-ended and differential components.
The short-to-battery protection integrated into the ADA4433-1 protects against both dc and transient overvoltage events, caused by an accidental shorts to a battery voltage up to 18 V. 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 ADA4433-1 features a high-order filter with −3 dB cutoff frequency response at 10 MHz and 45 dB of rejection at 27 MHz. The ADA4433-1 features an internally fixed gain of 2 V/V. This makes the ADA4433-1 ideal for SD video applications, including NTSC and PAL.
The ADA4433-1 operates on single supplies as low as 2.7 V and as high as 3.6 V while providing the dynamic range required by the most demanding video systems.
The ADA4433-1 is offered in an 8-lead 3 mm × 3 mm LFCSP package and is rated for operation over the wide automotive temperature range of −40°C to +125°C.
