Hello Sanjay, Thanks for the hint. Is the DAC81402 not just a dual DAC81401, then? I see that block diagrams in the respective data sheets do have some differences related to the sense inputs. Please can you clarify the differences between the two parts, apart from the DAC81402 being dual-channel? Being a single-channel part, I'd prefer to use the DAC81401 if possible; I'll post a block diagram shortly to illustrate how I had hoped the low-side current sense might work. Ian
