ADV7121KN80

Digital To Analog Converters Overview

The ADV7121KN80 is a triple, parallel word input loading, 10-bit digital-to-analog converter (DAC) manufactured by Analog Devices Inc. It features CMOS technology and operates within a commercial temperature range of 0°C to 70°C. The device utilizes a standard TTL input interface and provides high-impedance analog output current sources. It is housed in a 40-pin plastic dual in-line package (PDIP) with a maximum seated height of 5.08 mm. The nominal supply voltage is 5 V. This component is designed for video speed applications, supporting pipelined operation up to 80 MHz.

Digital To Analog Converters Feature Summary

• Triple 10-bit D/A converters integrated on a single monolithic chip
• 80 MHz pipelined operation speed
• Standard TTL compatible inputs and RS-343A/RS-170 compatible outputs
• High impedance analog output current sources

Digital To Analog Converters Applications

• High Definition Television (HDTV)
• High Resolution Color Graphics
• CAE/CAD/CAM Applications
• Image Processing
• Video Signal Reconstruction

Digital To Analog Converters Procurement Notes

Verify the specific speed grade suffix 'KN80' against the manufacturer's datasheet to confirm the 80 MHz performance rating. Ensure the PDIP-40 package dimensions match the design requirements. Check for RoHS compliance status as indicated in the official documentation. Confirm availability through authorized distributors as this may be a legacy part number.

Digital To Analog Converters Selection Notes

Select the ADV7121KN80 when a triple-channel DAC with 10-bit resolution and high-speed video processing capabilities is required. The 80 MHz operating frequency makes it suitable for HDTV and high-resolution graphics. Consider the PDIP-40 package if through-hole mounting is necessary. Verify that the system can accommodate the 5 V supply voltage and TTL logic levels.

Digital To Analog Converters Part Context

The ADV7121 series includes variants such as the ADV7121KN30 (30 MHz) and ADV7121KN50 (50 MHz). The KN80 designation specifically denotes the 80 MHz speed grade. Other packages available for the ADV7121 family include 44-pin PLCC and 48-lead TQFP options, offering flexibility for different board layout constraints.

Digital To Analog Converters Replacement Considerations

Direct replacements within the same family include the ADV7121KN30 and ADV7121KN50, which offer lower speed grades but share the same pinout and functionality. For higher integration, consider the AD9744 or AD9745, though these are dual-channel devices. Verify compatibility with existing TTL interfaces and power supply requirements when substituting.
