The very old TTL logic ICs need a regulated 5V supply with a lot of current.
You will be making the oldest and biggest hearing aid ever made.
The circuit and battery will be huge.
You like old parts, don't you?
The old DS1669 digital pot is linear. A volume control is supposed to be logarithmic.
Maxim-IC have some logarithmic digital volume controls.
Maybe im too "analog" in designing circuit
What is the different between linear volume control and logarithmic volume control?I mean in the way their perform?
From my understanding,volume control suppose to be linear.If we increase the volume,the output increase in time with volume.
Correct me if im wrong.
