This is part of my Instrument Control Board project in which I describe the choice of DAC, ADC and Op Amp. Component SelectionNo great science behind many of the components selected - mainly "do they do what I want?" and "price vs similar component".  So, for example, the choice of I2C isolator or Digital Isolator was really made around channels and required signal direction.  Confirmation of the chosen parts was made during the design to ensure (in my limited experience) they would su ...
Introduction jancumps, jc2048 and peteroakes are building an electronic load with what they call a Booster Pack control board to front end.  I've found it really interesting to look at what is being done and decided I wanted to have a go at something similar without just replicating what they have done.  I also wanted to have a go at playing with a DAC and ADC so it seemed like a good tie-in.  More specifically, these are the questions I'm asking myself: Could this be a generic c ...
I've been spending some time thinking about best using an ADC and I've done some weighing up of suitable components.  I've half settled on a Microchip MCP3248 rather than a TI ADS1115.  The Microchip has slightly better specs than the TI but it is limited in range on its inputs: -2.048V to +2.047V differential, 0V to +2.047V single ended; the TI has a more flexible option of ranges which expands its single-ended ranges, including a -4.096V to +4.096V, 0V to +4.096V single ended.   ...
