ADV7121KN50

Digital To Analog Converters Overview

The ADV7121KN50 is a high-speed, triple 10-bit digital-to-analog converter (DAC) manufactured by Analog Devices Inc. Designed for video and graphics applications, it integrates three independent DAC channels optimized for RGB signal processing. The device operates with an 80 MHz pipelined architecture, ensuring rapid data conversion suitable for high-resolution displays. It features TTL-compatible inputs and RS-343A/RS-170 compatible analog outputs. The component is housed in a 48-lead Thin Quad Flat Package (TQFP), supporting +5 V CMOS operation. This monolithic construction simplifies design for systems requiring precise video signal reconstruction and direct digital synthesis.

Digital To Analog Converters Part Context

The ADV7121 series belongs to Analog Devices' family of video-speed DACs. The 'KN50' suffix indicates the specific speed grade (50 MHz guaranteed performance within the 80 MHz capable device family) and the lead-free TQFP packaging variant. This part is distinct from the 8-bit variants like the ADV7120 and serves as a higher-resolution alternative for professional video and graphics interfaces.
