Question on the TLV2556

ABE OMRAN

Other Parts Discussed in Thread: TLV2556, TLC2578

I would like to use the TLV2556 to sample analog inputs in the range from -4.096V to +4.096V (or at least -2.048V to +2.048V). Can this be done? If so, can someone provide a schematic?

Thanks a lot.

Abe.

Hi Abe!

Welcome to the E2E Community! The TLC2556 cannot accept negative inputs directly, you'd have to scale the input and level shift to get your signals within the 0-Vref range of this ADC. Do you need all eleven channels? We might have something else that you can use (the TLC2578 perhaps?) if you can get away with only eight inputs.

Thanks tor the info Tom. I think I better scale down.
