ADV7123KSTZ140

Digital To Analog Converters Overview

The ADV7123KSTZ140 is a triple high-speed video digital-to-analog converter (DAC) fabricated in CMOS technology. It integrates three independent 10-bit DACs with complementary outputs, designed for high-performance video applications. The device supports a maximum throughput rate of 140 MHz and operates on a single 5 V or 3.3 V supply. Key features include TTL-compatible inputs, an internal 1.235 V voltage reference, and low power dissipation capabilities. Packaged in a 48-lead LQFP, it ensures guaranteed monotonicity to 10 bits and compatibility with RS-343A and RS-170 standards.

Digital To Analog Converters Feature Summary

• Triple 10-bit DACs with 140 MSPS throughput rate
• RS-343A/RS-170 compatible complementary outputs
• Internal 1.235 V reference and TTL-compatible inputs
• Low power standby mode (6 mW typical at 3 V)

Digital To Analog Converters Applications

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

Digital To Analog Converters Procurement Notes

Verify the specific speed grade suffix 'K' corresponds to the required 140 MHz operational frequency during procurement. Confirm package availability and lead times directly with Analog Devices or authorized distributors, as manufacturing baselines may shift. Ensure ESD precautions are observed due to moisture sensitivity.

Digital To Analog Converters Selection Notes

Select this component when a 140 MHz video DAC is required. For higher speeds up to 330 MHz, consider the J-grade variants. Ensure the system design accommodates the 48-lead LQFP footprint and provides adequate thermal management for power dissipation levels specified in the datasheet tables.

Digital To Analog Converters Part Context

This part belongs to the ADV7123 family of high-speed video DACs from Analog Devices. The K-stamped variant specifically denotes the 140 MHz performance grade, distinguishing it from the 50 MHz, 240 MHz, and 330 MHz versions within the same product line.

Digital To Analog Converters Replacement Considerations

Direct pin-compatible replacements within the same family include ADV7123JSTZ140 (330 MHz grade) or ADV7123KSTZ240 (240 MHz grade), provided the higher speed does not conflict with system constraints. Verify electrical parameters against the specific application requirements.
