In my project I use a 5-Way TCRT5000. This is a 5x digital IR sensor. I want to connect it to my Arduino Nano, but as I use most other pins, I want to convert the output of the sensors into an analog output using a DAC.
My requirements when using this sensor are:
5-bit Parallel Input
Analog Output (and not i2c)
I saw a chip that was fitting my purposes, Sparkfun AD5330, but it has been discontinued, and I cannot find a similar alternative. neither Adafruit not Sparkfun sell an alternative that suits both demands.
Has anyone used something similar or know of an alternative chip?

5 bit parallel input, do you mean you have 5 analog inputs?
How are the 5 analog inputs going to relate to the one analog output?
Why don't you want to use I2C to drive your DAC?
Thank you for your answers. I think that the R-2R ladder is the best choice here.
TomGeorge the sensor outputs 5 digital values, and I would like to use only one analog pin instead of 5 digital ones.
The idea is that the 5 outputs will be converted to a binary-represented voltage using a ladder or a DAC so it can be attached to one analog pin and then parsed by the arduino to know each of the sensors value.
