ADV7125JSTZ240

Digital To Analog Converters Overview

The ADV7125JSTZ240 is a triple high-speed digital-to-analog converter (DAC) fabricated in a monolithic CMOS process. It integrates three independent 8-bit video DACs with complementary outputs, designed for throughput rates up to 330 MSPS at 3.3 V operation. The device features TTL-compatible parallel data inputs and includes an internal 1.235 V voltage reference. It operates on a single +5 V or +3.3 V supply and supports industrial temperature ranges from −40°C to +85°C. The component is housed in a 48-lead LQFP package.

Digital To Analog Converters Feature Summary

• Triple 8-bit DAC architecture with 330 MSPS maximum throughput rate
• RS-343A/RS-170 compatible differential and single-ended analog outputs
• Integrated 1.235 V internal voltage reference with external compensation pin
• TTL-compatible digital interface with composite SYNC and BLANK control signals

Digital To Analog Converters Applications

• Digital video systems and signal reconstruction
• High resolution color graphics displays
• Digital radio modulation equipment
• Automotive infotainment units

Digital To Analog Converters Procurement Notes

Verify the specific grade suffix 'J' corresponds to the required industrial temperature range (-40°C to +85°C). Confirm that the 'STZ' designation aligns with the 48-lead LQFP package requirement. Ensure the '240' speed grade matches the system clock frequency needs, as performance varies between 5 V and 3.3 V operating modes.

Digital To Analog Converters Selection Notes

Select this component when a triple-channel video DAC with high bandwidth is required. The internal reference simplifies design by reducing external component count. Verify power supply constraints, as the 330 MSPS speed grade is specified for 3.3 V operation only, while lower speeds are supported at 5 V. Ensure PCB layout accommodates the 48-lead LQFP footprint and thermal requirements.

Digital To Analog Converters Part Context

The ADV7125 belongs to Analog Devices' high-speed video DAC family. The JSTZ240 variant specifically denotes the industrial temperature grade, LQFP packaging, and 240 MHz/330 MHz speed binning depending on supply voltage. It serves as a direct replacement for legacy video encoder chips requiring RGB conversion with integrated sync handling.

Digital To Analog Converters Replacement Considerations

Direct functional substitutes within the same series include the ADV7125KSTZ50 (50 MHz grade) and ADV7125WBSTZ170 (automotive grade). Verify pin compatibility and electrical specifications before substitution, particularly regarding operating temperature ranges and maximum clock frequencies.
