ADV7123JSTZ240

Digital To Analog Converters Overview

The ADV7123JSTZ240 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 direct interfacing with RS-343A and RS-170 standards. The device supports a maximum throughput rate of 330 MSPS and operates on a single 5 V or 3.3 V supply. Key electrical parameters include an internal 1.235 V reference, TTL-compatible inputs, and a DAC output current range from 2.0 mA to 26.5 mA. It features low power dissipation of 30 mW minimum at 3 V and includes a standby mode consuming 6 mW typical at 3 V.

Digital To Analog Converters Feature Summary

• RS-343A/RS-170 compatible differential outputs
• Internal 1.235 V voltage reference
• TTL-compatible digital inputs

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 suffix JSTZ240 against the manufacturer's ordering guide to confirm package type and temperature grade. Confirm RoHS compliance status as indicated in the datasheet revision history. Ensure availability through authorized distributors, as lead times may vary based on production schedules.

Digital To Analog Converters Selection Notes

Select this component for applications requiring high-speed conversion of RGB data into analog video signals. Ensure the system clock frequency does not exceed 330 MHz. Verify that the load impedance matches the 75 Ω requirement for RS-343A/RS-170 compatibility. Consider the 3.3 V or 5 V supply option based on system power constraints.

Digital To Analog Converters Part Context

The ADV7123 belongs to Analog Devices' family of high-speed video DACs. It is designed to replace older discrete video DAC solutions by integrating multiple channels and control logic onto a single chip. The JSTZ240 designation typically refers to the 48-lead LQFP package variant intended for industrial temperature ranges.

Digital To Analog Converters Replacement Considerations

Check for pin-compatible alternatives within the same product family if supply is limited. Verify that any substitute maintains the 330 MSPS throughput and 10-bit resolution requirements.
