Mar 8, 2020 at 21:21 | comment | added | Ron Beyer | @ElectronicLover If it does, then you can select something a little more powerful, like a PIC16F15344 which can run a sample less than 65ns, and is about the same price ($0.89 in qty 1). | |

Mar 8, 2020 at 21:02 | comment | added | Transistor | Are you running two accounts on this question? | |
Mar 8, 2020 at 21:01 | comment | added | ElectronicLover | @RonBeyer how about conversion time for each adc channel? are they in parallel? i think that the entire process with parts you've mentioned easily exceed the 100 us threshold, Am I wrong? | |
Mar 8, 2020 at 20:54 | comment | added | ElectronicLover | @vicatcu output of sensors? Yes they are buffered. | |
Mar 8, 2020 at 20:53 | comment | added | Ron Beyer | A cheap MCU with 13 analog inputs is probably cheaper than a few dozen discrete components, I think you may be focusing on the wrong thing... For example, the ATMEGA4809 has 20 ADC's and is $2.22 in qty 1 for a PDIP. If you want small space, go with the ATTiny1617 which is $0.92 and has 20 ADC's. | |
Mar 8, 2020 at 20:52 | comment | added | ElectronicLover | @vicatcu just 0 to 1 for desire line | |
Mar 8, 2020 at 20:50 | comment | added | vicatcu | re: inputs, what is the output impedance? are they buffered? | |
Mar 8, 2020 at 20:44 | comment | added | vicatcu | what output would you expect such a circuit to present to you? What circuits would be downstream consumers of it? What are the upstream sources of these analog voltages? | |
