Part Number: REF3212-EP Other Parts Discussed in Thread: REF3220-EP , REF3225-EP , REF3230-EP , REF3240-EP Hello,
These parts are shown to be –EP versions available (per TI doc sgzt005a.pdf and http://www.ti.com/pdfs/hirel/mltry/EP_Orderable_Release_List…
Hi John,
I'd probably recommend something simple like the uA7805. It should really only require a capacitor on its input and output, and should give you a reasonably stable 5V output over temperature and input supply.
As drawn, for a 50mV trip point…
Hi team,
My customer recently met the stability issue.
I try to help to analyze the phase margin.
Could you please help to check whether my setting is right?
Schematic :
Loop1:
Loop2 :
If the setting is right and good simulated phase margin, what is …
Hello Andrea,
I was thinking of a 3rd electrode placed immediately adjacent to B, but the schematic as drawn may work as well. Yes, try using the REF3225 to drive the 2.5V node. The INA826 should work in this configuration as well.
Hi,
I would like to replace LT1790-2.5 on a pcb already designed.
I think I have two options:
-REF2025 but I need to know if it works with Vbias(pin 1) connected to gnd(because pin 1 in LT is gnd) and Enable(pin 3) floating.
-REF3225 if it works with…
Other Parts Discussed in Thread: LMP7709 , REF3225 , REF3230 , OPA2227 , OPA4376 , LMP7704 Hi All,
Could someone give me more info about the VREFLO pins on the TMS320F28337? What are the voltage limits when using a ratiomatric reference? Could I just supply…
Other Parts Discussed in Thread: LMP91000EVM , LMP91000 , REF3225 Hello,I am using a 3-strip electrochemical sensor to measure concentration of H2O2.
I am using SPIO-4 with LMP91000EVM. I wonder which is the sampling frequency and how many bits per sample…
Other Parts Discussed in Thread: ADS1298 , REF3240 , REF3225 Hi!
I'd like to know more about the best practice in designing the hardware around the ADS1298 chip family. First off, I'm really satisfied with my results with these chips but there is always…
Stephan,
By using the temperature sensor to measure the DC code spread (or digital variation), you are measuring the variation of both the ADC and temperature sensor output, instead of ADC output only. Since the temperature sensor will vary with junction temperature…
