Hello All,
I'm working on a project for motor control using an A3979 Microstepping DMOS Driver from AllegroMicro. In order to minimize board size I will be using the output of a microchip microelectronic to set the voltages for current ref and stepping mode. So I'm thinking of anput of 5Khz 3.3V PWM signal, not sure about that yet, but I basically want to voltages from 200mV up to around 2.2V.
I'm trying to figure out how can I accomplish this? Low pass filter? Op-Amp?
