Part Number: REF3040 Hi,
I'm implementing an application that requires running the MCU only on battery power in the event of a power outage (expected consumption around 25uA). The request is to use a very small battery and therefore I would like to be…
Part Number: REF3040 Hi, TI Team.
I have found data sources of failure rate namely:
1) www.ti.com/.../estimator.tsp
2) https://www.ti.com/quality/docs/estimator.tsp?OPN=REF3040AIDBZT&CPN=&partNumber=REF3040#resultstable
Which number should I…
Part Number: REF3040 I refer to the ads8332 datasheet to design the voltage reference circuit, but the final output voltage is 20mV more, and my design voltage is 4.096V，where R239 is 0ohm
Part Number: LMP2012
Tool/software:
Shown below is a thermocouple amplifier circuit implemented using the LMP2012.
Using K type thermocouple, the circuit produces the expected response of ~ 2.77mV/°C. (gain of 67.67)
In the same system there are PWM…
Part Number: DAC8565 Customer was designing DAC8565 to replace AD5689 in the new projects, to generate analog output, one range with -3.3V to 3.3V, and the other with 0V to 3.3V.
Could you please help review the schematic to see any suggestions? Their…
Hi,
Sorry but as you probably saw, REF3040 is the recommended part on the DS. I bet all the parameters measured during characterization and production test of the device were and are taken with that reference. I doubt you will get any improvement if you…
Hi, Zhang
As shown in pic below. The thermistor and R80 divide the output voltage of U30-REF3040, and thermistor is 10KΩ, coresponding 25℃. So the Vth is 1V when temperature is 25℃. I set Vset=1V, coresponding 25℃.
When I set Vset=1V, I actually…
Part Number: XTR117 Hi TI
1. What is the direct voltage difference between the V+and Vreg pins of XTR117 chip?
2. Can REF3040 be used as the voltage reference source of XTR117?
3. The customer uses RC filtering+XTR117 to achieve the output of…
Part Number: LOG114EVM Other Parts Discussed in Thread: LOG114 , OPA365 The LOG114EVM design differs from the recommendations in the LOG114 datasheet. The differences are:
1) The LOG114 datasheet in Figure 2 uses a REF3040 to provide a 4.096V signal to…
Hello Mark,
Please find below the comparison table between the various reference chips.
These were some of the parts that we looked at and we have used REF3040 and LM4140 in our higher channel density devices.
LM4140
REF3040
REF3140
REF3…
