The document describes the features and characteristics of ADA4430-1, an ultralow power video filter. The filter has 6th-order performance with 1 dB flatness up to 8 MHz and 50 dB rejection at 27 MHz. It has ultralow power-down current and quiescent current, excellent video specifications, SAG correction, and allows for the use of small capacitors in AC-coupled outputs. Additionally, it features low input bias current and a wide operating temperature range.
The ADA4430-1 is a fully integrated video reconstruction filter designed for portable video applications such as media players, gaming consoles, and cell phones. It offers ultralow power consumption, a power‑down current of only 0.1 µA typ, and a low quiescent current of 1.85 mA typ, while maintaining excellent video specifications like 1 dB flatness to 8 MHz and 50 dB rejection at 27 MHz.
The device operates from a single supply of 2.5 V to 6 V, provides rail‑to‑rail output, and includes features such as SAG correction, on‑chip DC offset, and high input‑to‑output isolation when disabled. It is supplied in a 6‑lead SC70 package and is rated for an extended automotive temperature range of –40 °C to +125 °C.
