by KlausST, supermoderator on EDABoard.com Here I’d like to show how to design a DAC controlled high -side constant current source. Since it is often used as 0..20mA (or 4..20mA) current loop interface, we will focus on the interface requirements. * low speed ( maybe some 10Hz up to some kHz) * high precision * […]
