Part Number: REF3025 Other Parts Discussed in Thread: REF3125 , REF3225 , REF1933 , REF1925 Hi Team,
REF3025 and REF3033 was used in customer's project.There is a problem when REF30XX is used for offset voltage.
Here is the schematic on customer site…
Part Number: REF3025 Other Parts Discussed in Thread: INA828 , REF30 Hi,
When using REF3025 as the voltage reference for INA828, the output of REF3025 is changed to 2.64V. And REF3025 could work when it's not connected to INA828. Could you please give…
Part Number: MSPM0L1306 Other Parts Discussed in Thread: SYSCONFIG Hi Champs!
Customer is finalizing his 1st MSPM0L PCB and raised some BSL/pin related questions:
1.
For the ADC we will use an external reference voltage source (REF3025). We will…
Hi Bob B,
you would suggest making the measurement ratiometric to cancel this drift in the conversion result.
=> It means i need use External reference (REFP0, REFN0) and Current sources on, 500 µA.
Can i use analog supply (AVDD – AVSS) used as…
Jackson
sorry, there is an input error!
The input voltage minimum is 3.3V.As there is no the curve of dropout voltage vs load current with different temperature and no data for REF3030(data listed in datasheet is for REF3025),customer wants to know…
Part Number: REF3012 About Datasheet of REF30xx series, 7.6 Typical Characteristics are described only REF3025 specification.
Is there REF3012 Characteristics like the REF3025? （Expect Vout specification, is these REF3025 spec the same as REF3012?）…
Part Number: REF3012 Customer found when no load, the output voltage of REF3012 and REF3025 are too high and violate the spec in the datasheet. please find the measured values here.
Could you explain why the behavior is and is this normal behavior?…
Hi Brian,
The table on page 14 says the following: "over recommended operating conditions, TA = 25°C ( unless otherwise noted )". On the "Deviation of reference input voltage over full temperature range" specification, there is a note (1) . Under the…
Hi ttd,
You are correct, in saying by adding this additional ground tracking system in place, there will be a compromise in the applied reference voltage.
But the advantage with this scheme is that as long as you choose resistors with 0.1% tolerance…
Hi Arin,
The LM4120 is a "I" grade device. This means that it is "I" for industrial and thus a ambient temperature of -40C to 85C as shown in the RoC.
The Tj, Juction temperature, can be higher up to 125C but we do not recommend to use at an ambient…
