Product Details
The ADA4433-1 is a differential output, fully integrated video reconstruction filter 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 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 fully differential input to a differential output or as a single-ended input to a differential output, allowing it to easily connect to both differential and single-ended sources. It is capable of driving twisted pair or coaxial cable with minimal line attenuation. Differential signal processing reduces the effects of ground noise, which can plague ground referenced systems. The ADA4433-1 is ideal for differential signal processing (gain and filtering) throughout the signal chain, 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 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 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 featurea 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 2.6 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, rated for operation over the wide automotive temperature range of −40°C to +125°C.
