ADV7125KSTZ140

Digital To Analog Converters Overview

The ADV7125KSTZ140 is a triple high-speed digital-to-analog converter (DAC) fabricated in a CMOS process. It integrates three independent 8-bit video DACs with complementary outputs and a standard TTL input interface. The device supports a maximum throughput rate of 140 MHz, suitable for high-resolution graphics and video signal reconstruction. It operates on a single +5 V or +3.3 V power supply and includes an internal 1.235 V voltage reference. Key features include low power dissipation, a standby mode, and compatibility with RS-343A and RS-170 standards.

Digital To Analog Converters Feature Summary

• Triple 8-bit DAC architecture with complementary analog current outputs

Digital To Analog Converters Procurement Notes

Verify the specific speed grade suffix '140' to confirm the 140 MHz operational limit. Ensure the package type matches the design requirements, as the ADV7125 series is available in both LQFP and LFCSP formats. Confirm RoHS compliance status for the specific manufacturing lot before integration into production.

Digital To Analog Converters Selection Notes

Select this component when a 140 MHz throughput rate is sufficient for the target application. Verify that the system can accommodate the required RSET resistor values to set the full-scale output current range between 2.0 mA and 26.5 mA. Ensure the PCB layout supports the necessary decoupling for the analog and digital supplies to maintain signal integrity.

Digital To Analog Converters Part Context

The ADV7125KSTZ140 belongs to the ADV7125 family of triple 8-bit video DACs from Analog Devices. This family offers various speed grades, including 50 MHz, 140 MHz, 240 MHz, and 330 MHz variants. The KSTZ suffix indicates a specific temperature and packaging configuration within this product line.

Digital To Analog Converters Replacement Considerations

Direct replacements within the same speed grade include other ADV7125 variants with the 140 MHz designation. For higher performance needs, consider the 240 MHz or 330 MHz grades of the ADV7125 series, provided the pinout and thermal requirements remain compatible.
