Part Number: REF3233 Other Parts Discussed in Thread: REF3433 Hi Team
Good day!
Customer want to know that theta JC and theta JB for REF3233
Best regards Aosker Lau
Part Number: REF3233 Other Parts Discussed in Thread: REF3433 Hi team,
The customer uses REF3233. The attach is his schematic. The output voltage of REF3233 is connected to ADC.
The input voltage is 3.8V. The ENABLE pin is controlled by the GPIO of MCU…
Part Number: REF3233 Other Parts Discussed in Thread: REF3230 , REF3130 , REF3030 , LM4132 , REF3430 Hi Team,
Customer uses REF3233 for C2000 (28377D) SAR ADC VREF.
They found strange problem with REF3233 that cause the ADC reading random offset. (It won…
Part Number: REF3233 Hi All, Currently, we are developing the product for the Train control systems for railway. In which, we have selected the REF3233 for Analog section power supply.Our end product needs to be noise protected system for certification…
Part Number: REF3233 Hi,
In our application we don't get 3.3V from REF3233-EP as expected but 3.24V to 3.28V.
After switching the REF3233-EP (see attached schematic) on/off several times, the output voltage then become 3.3V.
On the attached scope…
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 Biser,
Thanks for your reply!
I think the 1.8V +/- 5% is the power supply requirement for the VDDA_ADC. The accuracy that customer asked is the accuracy of the reference voltage when taking VDDA_ADC as the reference.
If an external voltage is provided…
Hello,
So I draw a circuit to illustrate the ferrite bead: [routing of VDD through small value series R (<10Ω) w/that resistor in series w/ "small ferrite bead" and the bead bypassed by small value cap. (w/both bead & cap very close to VDDA)]…
Other Parts Discussed in Thread: REF3233 , LM7705 According to the datasheet, VREFA+ must be at least 2.4 volts, and can be up to VDDA. This is easy to ensure - you just link VDDA with VREFA+ even if you are not using an external precision reference.
