Overview
The ADA4417-3ARMZ-RL, produced by Analog Devices Inc., is a low-cost, fully integrated video reconstruction filter specifically designed for consumer high definition video applications. This device offers a comprehensive solution for video filtering and driving, making it ideal for various high-definition video environments. It features a 38 MHz, 1 dB bandwidth and a sixth-order Butterworth response with group delay equalization, ensuring minimal phase distortion and high stop-band attenuation. The ADA4417-3 operates on a single supply voltage range of 3.3 V to 5 V and is well-suited for power-critical applications due to its low quiescent current and power-down capability.
