ADV7123JST240-REEL

Digital To Analog Converters Overview

The ADV7123JST240-REEL is a triple high-speed video digital-to-analog converter (DAC) fabricated in CMOS technology. It integrates three independent 10-bit DACs capable of a 330 MSPS throughput rate. The device features TTL-compatible inputs, an internal 1.235 V reference, and complementary current outputs designed to drive RS-343A/RS-170 standards into 75 Ω loads. Operating on a single 5 V or 3.3 V supply, it delivers low power dissipation with a dedicated standby mode. Packaged in a 48-lead LQFP, it supports industrial temperature ranges from -40°C to +85°C.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'REEL' against the manufacturer's ordering guide to confirm tape-and-reel packaging quantities. Confirm that the '240' grade designation aligns with the required clock frequency specifications for the target application environment.

Digital To Analog Converters Selection Notes

Select this component when a triple-channel, high-speed video DAC is required. Ensure the system design accommodates the 48-lead LQFP package dimensions. Verify that the host logic operates within the specified TTL input voltage levels and that the power supply rails match the 5 V or 3.3 V operational requirements.

Digital To Analog Converters Part Context

This part belongs to the ADV7123 series of high-speed video DACs from Analog Devices. It is functionally identical to the ADV7123JSTZ240 but differs in packaging format. The series is designed for professional video applications requiring precise RGB conversion with minimal power consumption.

Digital To Analog Converters Replacement Considerations

The ADV7123JSTZ240 is a direct equivalent with identical electrical characteristics. Check the ordering guide for other speed grades such as the ADV7123KST140-RL if lower clock frequencies are sufficient for the design.

Digital To Analog Converters FAQ

What is the maximum clock frequency supported by this device?

The ADV7123 supports a maximum clock frequency of 330 MHz.

How is the full-scale output current controlled?

The full-scale output current is set by connecting a resistor (RSET) between the RSET pin and ground. For nominal video levels into a doubly terminated 75 Ω load, RSET is typically 530 Ω.

Does the device include an internal voltage reference?

Yes, the ADV7123 includes an internal 1.235 V reference. A 0.1 μF ceramic capacitor must be connected between the COMP and VAA pins for stability.
