MAX9590ETU+

Video Amps And Modules Overview

The MAX9590ETU+ is a TFT-LCD gamma reference buffer featuring 14 programmable voltage references and four static references. It operates with an analog supply voltage range of 9V to 16.5V and a digital supply of 2.7V to 5.5V. The device includes two register banks for storing distinct gamma value sets, enabling output switching between banks in less than 0.5µs. Each programmable channel utilizes an 8-bit DAC with isolation buffers capable of sourcing or sinking up to 400mA peak current. Outputs remain tri-stated during wake-up to prevent transient currents.
