Hello, I'm trying to select an ADC right now and I'm a bit confused by all the different ADC input types and which is the right one for me. The signal that I'm converting is coming from the LA 55-P current transducer. It's a bipolar signal and will swing from +5V to -5V. Do I need single ended bipolar input? If you could shed some light on this, it would be much appreciated. Also, if you could provide an ADC recommendation, that would be much appreciated as well. The requirements are as follows 1 input channel Sample rate of 1MSPS or higher >12 bits of resolution Less parts, the better. Faster assembly and lower elements in the signal chain (lower error) ADCs need to be able to be daisy chained Enhanced SPI would be preferred. We need to transmit signals over a cable so the lower speed signals would be preferred No BGA or LGA. We need to solder these boards by hand. QFN is doable, but not preferred. I was looking at the ADS8691 . Would this be a good fit? Is the input type correct? I am by no means an expert in analog design so if I'm misunderstanding anything in these requirements, please don't hesitate to point it out. I would appreciate that. Thanks!
