ADV7125JSTZ330

Digital To Analog Converters Overview

The ADV7125JSTZ330 is a triple high-speed, digital-to-analog converter (DAC) fabricated on a single monolithic CMOS chip. It integrates three independent 8-bit video DACs with complementary outputs, a standard TTL input interface, and a high-impedance analog output current source. The device operates on a single +5 V or +3.3 V power supply and supports a maximum throughput rate of 330 MSPS when powered at 3.3 V. Key features include RS-343A/RS-170-compatible outputs, an internal 1.235 V reference, low power dissipation, and a low-power standby mode. It is housed in a 48-lead LQFP package and qualified for automotive applications.

Digital To Analog Converters Procurement Notes

Verify the specific suffix JSTZ330 against the manufacturer's ordering guide to confirm the 330 MHz grade and LQFP package variant. Ensure compatibility with system requirements for 3.3 V operation, as the maximum throughput speed is dependent on the supply voltage. Confirm RoHS compliance status for the specific manufacturing batch.

Digital To Analog Converters Selection Notes

Select this component for designs requiring high-speed RGB video conversion with TTL logic interfaces. The 330 MHz grade is suitable for high-resolution graphics systems operating at 3.3 V. Ensure the design accommodates the 48-lead LQFP footprint and provides adequate thermal management, as power dissipation increases with clock frequency and analog load settings defined by the RSET resistor.

Digital To Analog Converters Part Context

The ADV7125 series comprises triple 8-bit high-speed video DACs available in multiple speed grades and packages. The JSTZ330 designation indicates the 330 MHz performance grade packaged in a 48-lead LQFP. This part belongs to a family designed for direct interfacing with CRT controllers and graphics processors, offering integrated synchronization and blanking controls within a single monolithic CMOS structure.

Digital To Analog Converters Replacement Considerations

Direct replacements within the same speed grade and package include other variants from the ADV7125 family, such as the ADV7125KSTZ50 (50 MHz), ADV7125BSTZ140 (140 MHz), or ADV7125CSTZ240 (240 MHz). These share identical pinouts and functionality but differ in maximum clock frequency specifications.
