Product Introduction
The ADA4432-1 (single-ended output) and ADA4433-1 (differential output) are fully integrated video reconstruction filters with integrated overvoltage protection (short-to-battery [STB] protection) and short-to-ground (STG) protection on the outputs, offering excellent video performance and low power consumption. With STB protection and robust ESD tolerance, they provide outstanding protection in harsh automotive environments.
The ADA4432-1 is a single-ended input/single-ended output video filter capable of driving back-terminated long cables.
The ADA4433-1 is a fully differential video filter that can be used as a fully differential input-to-differential output or single-ended input-to-differential output, making it easy to interface with differential and single-ended signal sources. It can drive twisted-pair or coaxial cables with minimal line attenuation. Differential signal processing reduces the impact of ground noise on ground-referenced systems. The ADA4433-1 is suited for differential signal processing (gain and filtering) throughout the entire signal chain, greatly simplifying conversion between single-ended and differential components.
The ADA4432-1 and ADA4433-1 integrate short-to-battery protection, guarding against DC and transient overvoltage events caused by accidental battery short circuits that can produce voltages up to 18 V. This STB protection technology eliminates the need for large output coupling capacitors and other complex circuitry to protect standard video amplifiers, saving board space and cost.
The ADA4432-1 and ADA4433-1 incorporate a high-order filter with a −3 dB cutoff frequency at 10 MHz and 45 dB rejection at 27 MHz. They also feature an internal fixed gain of 2 V/V, making them well suited for standard-definition video applications including NTSC and PAL.
The ADA4432-1 and ADA4433-1 operate from a 2.6 V to 3.6 V single supply while providing the dynamic range required by the most demanding video systems.
The ADA4432-1 and ADA4433-1 are available in 8-lead, 3 mm × 3 mm LFCSP packages. The ADA4432-1 is also available in a 6-lead SOT-23 package. All devices are rated over the −40°C to +125°C extended automotive temperature range.
