Does TI have a Successive Approximation Register IC or logic diagram?
Hi Handy Andy,
We have quite a few SAR ADCs available, and while the basic operation for them is the same there are slight differences depending on the number of inputs, interface type, etc. I'd be happy to help you select a device if that is your goal, but I would need more info on what you are looking for (number of inputs, resolution, speed, interface type, etc.)
For more general information on SAR ADC operation and designing with a SAR, I recommend checking out our Precision Lab video series covering ADCs.
All of our devices will be a complete system: sample/hold circuitry, comparator, register, DAC, and possibly other parts depending on device. You may be able to find a way to use discrete components to build a discrete register, but we don't have a standalone register.
As far as the devices we have, I'd recommend considering the TLC0820A. Parallel at such a low resolution is unusual these days, so we don't have many options there.
