Other Parts Discussed in Thread: LM109 , LM317 , REF102 , REF02 I need two precision +/- rails with +/- 10 mV margin. I tried using non-inverting amps with a ref for the positive sides, and I tried using inverting amps with the same ref for the negative…
Part Number: ADS1100 Other Parts Discussed in Thread: REF02 , ADS1110 , ADS1118 , ADS1115
Hello there,
my question is directed at AD converters ADS1100 that draw their reference voltage from Vdd. In other words, supply voltage is the reference voltage…
Part Number: DAC8750EVM Other Parts Discussed in Thread: DAC8750 , DAC8760 , REF02 , , DAC8760EMC-EVM
Hi,
so bought EVM from mouser, comes with no disk... OK, go to TI website.. not easy to find but eventually found it ( I think) sboc432b.zip

Hello Anthony,
It appears that you have a timing issue in your communications. If you could capture the waveforms using a logic analyzer or an oscilloscope, that would be helpful.
If I am reading your code correctly, it appears you have /CONVST inverted…
Hi Jimbo,
I see that you like to use our full differential op amplifier, and we are very appreciative.
The Vref input requirement is a low impedance source, which means that it may be a voltage source that is capable to source and sink (Vref bandgap…
Other Parts Discussed in Thread: DAC8574 , ADS1220 , REF02 , TIPD125 Hello,
This is the first time I have used a precision DAC so maybe there is something simple that I am missing.
I am using a DAC8574 to drive current source/sink circuits as part…
Hi Christian
It’s OK for the voltage reference. I will try the shunt reference you say in my prototype, along with an AD series architecture (REF02) so that I can compare the performances.
I am aware of the ADS1282EVM-CVAL. I didn’t try it because…
Hi Leonardo,
Yes, assuming the current requirements are acceptable the REF02 would meet your needs at a reduced cost.
Don't you need 2 external DAC outputs for fine microstepping? And as you said the challenge will be isolating the DAC output(s) across…
