ADV7123JSTZ330

Digital To Analog Converters Overview

The ADV7123JSTZ330 is a triple high-speed, 10-bit digital-to-analog converter (DAC) fabricated in a monolithic CMOS process. It features a 330 MSPS throughput rate and supports single-supply operation at 5 V or 3.3 V. The device includes three independent DAC channels with complementary outputs, designed to drive RS-343A/RS-170 compatible loads. Key specifications include an internal 1.235 V reference, TTL-compatible inputs, and low power dissipation of 30 mW minimum at 3 V. It operates within an industrial temperature range of −40°C to +85°C.

Digital To Analog Converters Feature Summary

• 330 MSPS maximum throughput rate for high-speed video applications
• Triple 10-bit DACs with complementary differential outputs
• Internal 1.235 V voltage reference and TTL-compatible digital inputs
• Low power standby mode consuming 6 mW typical at 3 V

Digital To Analog Converters Applications

• Digital video systems supporting resolutions up to 1600 × 1200 @ 100 Hz
• High resolution color graphics generation
• Video signal reconstruction and processing
• Instrumentation requiring precise analog output

Digital To Analog Converters Procurement Notes

Verify the specific suffix JSTZ330 confirms the 330 MHz grade and industrial temperature rating (-40°C to +85°C). Ensure the ordering code matches the Rev. D datasheet requirements. Confirm package type is 48-lead LQFP. Check for Pb-free compliance status as specified in the manufacturer's documentation.

Digital To Analog Converters Selection Notes

Select this component when a 330 MSPS sampling rate is required for RGB video conversion. The internal reference simplifies design by reducing external components. Ensure the system clock does not exceed 330 MHz. Verify that the load impedance matches the RS-343A/RS-170 standards for proper current sourcing capabilities.

Digital To Analog Converters Part Context

The ADV7123 series comprises multiple speed grades including 50 MHz, 140 MHz, 240 MHz, and 330 MHz variants. The JSTZ330 designation specifically identifies the highest speed grade within the family. All variants share the same 48-lead LQFP package and functional pinout, differing primarily in timing specifications and maximum operating frequencies.

Digital To Analog Converters Replacement Considerations

Direct replacements within the same speed grade are limited. Lower speed grades (e.g., ADV7123JSTZ240) may function if timing margins allow, but performance will be reduced. Higher speed grades are not available in this specific package configuration.
