volume attenuator and LDR

[arivel]

Hi everyone .
what I'm about to ask you is for an audio volume attenuator.
after reading many positive reviews on the system that uses LDRs I thought of using 2 CD-40193 binary counters that control a LOGDAC AD7118 chip which in turn controls two pairs of LDRs.
there is a problem, the AD7118 chip is no longer in production and therefore I thought about the possibility of replacing it with an MDAC.
the question is as follows: what is the difference between MDAC and LOGDAC (ad7118)

The relationship of Vdacout to Binary value in, the MDAC has a linear
transfer relationship, the 7118 a logarithmic response.

There are pushbutton controlled stereo solutions there.
