ISL55290IUZ

Overview

The ISL55290IUZ is a dual-channel composite video amplifier manufactured by Renesas Electronics under the Intersil brand. It features an 800 MHz gain-bandwidth product and a 268 V/us slew rate for high-speed signal processing. The device operates on single supplies of 1.5 V to 3 V or dual supplies of ±1.5 V to ±2.5 V. Key electrical parameters include a 500 µV input offset voltage, 40 µA input bias current, and 1.2 nV/√Hz input voltage noise density. It is housed in a 10-lead MSOP package with a shutdown feature and operates within a temperature range of -40°C to +85°C.
