ADV7123JST240

Digital To Analog Converters Overview

The ADV7123JST240 is a triple high-speed video digital-to-analog converter (DAC) fabricated in a monolithic CMOS process. It integrates three independent 10-bit DACs with complementary outputs, designed for high-performance video applications. The device supports a throughput rate of up to 330 MSPS and operates on a single 5 V or 3.3 V supply. Key features include TTL-compatible inputs, an internal 1.235 V reference, and low power dissipation. It is housed in a 48-lead LQFP package and functions within an industrial temperature range of −40°C to +85°C.

Digital To Analog Converters Feature Summary

• Triple 10-bit DACs with 330 MSPS throughput rate
• RS-343A-/RS-170-compatible differential outputs
• Internal 1.235 V voltage reference
• Low power standby mode (6 mW typical at 3 V)

Digital To Analog Converters Applications

• Digital video systems (1600 × 1200 @ 100 Hz)
• High resolution color graphics
• Video signal reconstruction

Digital To Analog Converters Procurement Notes

Verify the specific speed grade suffix (e.g., JSTZ240 indicates 240 MHz grade) against the required system clock frequency. Confirm that the 48-lead LQFP package matches the PCB footprint. Ensure the design accounts for the industrial temperature range (-40°C to +85°C) if operating outside standard commercial limits.

Digital To Analog Converters Selection Notes

Select this component when a triple-channel, high-speed video DAC is required. The 10-bit resolution and 330 MSPS rate suit high-resolution graphics. Check the RSET resistor value to set the full-scale output current (2.0 mA to 26.5 mA). Ensure the driving logic provides TTL-compatible levels for data and control inputs.

Digital To Analog Converters Part Context

The ADV7123 belongs to Analog Devices' high-speed video DAC family. It is part of the ADV7123 series, which includes variants with different speed grades and packaging options. The 'JSTZ240' designation typically refers to the 240 MHz performance grade in a lead-free LQFP package.

Digital To Analog Converters Replacement Considerations

Direct pin-to-pin replacements within the same family include other speed grades of the ADV7123, such as the ADV7123JSTZ140 (140 MHz) or ADV7123JSTZ50 (50 MHz), provided the lower throughput rates meet system requirements.
