You have to check for devices with suitable specification from Maxim, Analog Devices, Intersil or other vendors that make digital potentiometers. Unfortunately there's no exact DS1669 replacement.

my goodness then what to do sir ? :shock:
how to create it ? i want exactly the function it had

Hi all,

As FvM says DS1669 is no longer available in all version, luckily for me I have 8 pieces of each DS1669 10K, 50K, 100K, versions in my private stock for projects.

All depends what you plan to make, you can use dig pot with 255 or 1000 steps if needed.

Use dual dig pot (in one device two dig pot), you can find in catalogs, or always you can use two dig pot separately.
