Various diagram

This digital-to-analog converter (DAC) integrated circuit is designed for lowest noise performance, both radiated and conducted noise. A recommended connection diagram for the ADV7123 is shown in the following schematic diagram.

According to the ADV7123 datasheet, this device consists of three high speed, 10-bit, video DACs with complementary outputs, a standard TTL input interface, and a high impedance, analog output current source. It used to be applied in digital video systems, image processing, digital radio modulation, color graphics and more.

Description

These devices are monolithic timing circuits capable of producing accurate time delays or oscillation.
In the time delaymode of operation, the timed interval is controlled by a single external resistor and capacit
or network. In the astable mode of operation, the frequency andduty cy clemay beindependently
controlled with two external resistors and asingle external capacitor.
