ADV7125KSTZ50

Digital To Analog Converters Overview

The ADV7125KSTZ50 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, 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 supply and supports throughput rates up to 330 MSPS at 3.3 V. Key specifications include an internal 1.235 V reference, RS-343A/RS-170 compatible outputs, and guaranteed monotonicity to eight bits. It is housed in a 48-lead LQFP package and functions within an industrial temperature range of −40°C to +85°C.

• Automotive infotainment units
• Image processing and instrumentation

Digital To Analog Converters Procurement Notes

Verify the specific grade suffix 'K' against the manufacturer's ordering guide to confirm the exact throughput performance class and temperature rating. Ensure the 48-lead LQFP package dimensions match the target PCB footprint. Confirm RoHS compliance status for the specific manufacturing lot if required by regulatory standards.

Digital To Analog Converters Selection Notes

Select this component when a triple-channel, high-speed video DAC with TTL compatibility is required. The device supports both 5 V and 3.3 V logic levels, but maximum throughput speeds are achieved at 3.3 V. Designers must account for the 1-cycle pipeline delay between digital input latching and analog output transition. External RSET resistors are necessary to set the full-scale output current range.

Digital To Analog Converters Part Context

The ADV7125 belongs to Analog Devices' family of high-speed video DACs. The 'K' suffix typically denotes a specific speed bin or quality grade within the product line, while 'STZ' indicates the 48-lead LQFP package and lead-free construction. Other variants in the series may offer different packages like LFCSP or different speed grades such as 50 MHz or 140 MHz.

Digital To Analog Converters Replacement Considerations

Direct pin-compatible replacements within the same package and electrical specification should be sourced from the official ADV7125 ordering guide. Verify that any substitute maintains the 330 MSPS throughput requirement and TTL input compatibility.
