Overview
The ADV7127JRU240, 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 a 10-bit video DAC with 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 requires only a clock to function. The ADV7127 is available in 28-lead SOIC and 24-lead TSSOP packages, with the TSSOP package including a power-down mode and an on-board voltage reference circuit.
