SUMMARY

The discussion focuses on finding a pin-compatible alternative to the DAC0830, an 8-bit multiplying DAC designed for compatibility with microprocessors like the 8080 and Z80. Users suggest checking distributors such as Digikey, Newark, and Allied for availability of the DAC0832, a similar part. Additionally, they recommend exploring Maxim's inventory and contacting various chip manufacturers like Infineon, Atmel, and Microchip for potential alternatives. The conversation highlights the challenge of sourcing components in remote locations, such as South Africa.

PREREQUISITES
  • Understanding of DAC (Digital-to-Analog Converter) functionality
  • Familiarity with microprocessor interfacing, specifically with the 8080 and Z80 architectures
  • Knowledge of electronic component sourcing and distributor platforms
  • Experience with SMD (Surface-Mount Device) to DIP (Dual In-line Package) conversion techniques
NEXT STEPS
  • Research the specifications and compatibility of the DAC0832 as a replacement for the DAC0830
  • Explore Maxim Integrated's product offerings for alternative DAC solutions
  • Investigate SMD to DIP adapter boards for integrating different ICs
  • Contact chip manufacturers directly to inquire about pin-compatible DAC alternatives
USEFUL FOR

Electronics engineers, hobbyists, and procurement specialists seeking alternatives to the DAC0830 for projects involving microprocessor interfacing and component sourcing challenges.

does anyone know of another part similar to this dac?
like a pin compatible one? because this one is not readily available here, (even though it states that they are in full production on the national website)

"The DAC0830 is an advanced CMOS/Si-Cr 8-bit multiplying
DAC designed to interface directly with the 8080, 8048,
8085, Z80®, and other popular microprocessors."
"The DAC0830 series are the 8-bit members of a family of
microprocessor-compatible DACs (MICRO-DAC™)."
from the National Semi website.

thanks :)

Digikey has them:

So does Newark:

So does Allied:

There has to be a distributor close to you that has them.

You can look through Maxim's inventory to see if they have a part. Start calling reps(or e-mailing) from the various chip manufacturers. Try Infineon, Maxim, Atmel, Microchip, Intersil...

Another option is to build a plug-in module using other IC's. They make these neat little SMD to DIP boards that would allow you to use something from another manufacturer.

i don't know who allied is... but under that link there's a 'quantity in stock' and a 0 in that column.
