I'm currently getting the parts together to build a Peter Daniel and Bobken DAC;
Pushing the limits of TDA1543 NOS DAC
My question is to do with the shunt regulator, I understand the AD811 voltage regulator part, and realise the LM825 is drawn in backwards, as mentioned here;
Pushing the limits Regulator
But I don't know enough to figure out the CSS/BSP129 current/voltage source calcs and how it provides the constant current?
Could someone please give me a hand and point me in the right direction or give a little explanation to me how on this part works including some basic calcs?
Thanks,
Adam.
