Overview
The ADV7127KRU50-REEL, produced by Analog Devices Inc., is a high-speed, 10-bit digital-to-analog converter (DAC) integrated on a single monolithic CMOS chip. This device features an on-board voltage reference, complementary outputs, a standard TTL input interface, and high impedance analog output current sources. It operates on a single 5 V or 3.3 V power supply and is packaged in a 24-lead Thin Shrink Small Outline Package (TSSOP). The ADV7127 is designed for applications requiring high-speed video conversion and low power dissipation.
