Part Number: REF3130 Dear Pro，
The output voltage of some chips is inaccurate.See the figure below for the outsourcing circuit of the voltage reference chip: 3.3VDC input, and the voltage of 3.0VDC is generated as the reference voltage of the single…
Part Number: REF3130 Other Parts Discussed in Thread: TLVH431 Hi E2E,
Good day.
Our customer is looking for the Total Power Dissipation (Pd) and Maximum Case Temperature (Tcmax) of REF3130AIDBZR and TLVH431AQDBZR. This information is not in the datasheet…
Part Number: ADS7870 Other Parts Discussed in Thread: REF3130
Hi! We have been using the ADS7870 for a few years. Originally we used the internal 2.5 volt reference. However we recently redesigned and started to use an external 3.0 volt reference. We…
Hi Ken,
Even at 25°C, using a 3.3V input voltage is risky. If the voltage were to drop below 3.3V when the load current is 25 mA due to error in the power supply from an LDO or DC/DC converter, then there is also risk of the device not operating properly…
Part Number: TMS320F28377S Other Parts Discussed in Thread: REF3130 , TMS320F28379D , CONTROLSUITE , C2000WARE Dear All,
We are working on TMS320F28377S. We are using DAC - B to set output current limit of external module.
We are using TI's REF3130…
Hi Frank,
For the ADC Reference voltage (3.0V), I am using REF3130. and its output I have connected directly to all 4 ADC's of the MCU.
But, I notice that, In the launchpad of the MCU, there is a REF5030IDGKT regulator followed by 2 voltage followers…
Hello,
Here is how I would calculate the minimum and maximum error for -10°C to 65°C when taking only initial accuracy and temperature drift into consideration:
Temperature drift max error = 75°C * 60 ppm/°C = 4500 ppm
Initial Accuracy Max Error…
Hi Shalom,
the chapter with the RC filtering in the datasheet of REF3230 sounds like a bad choke to me. The RC filter seems to be the fix of an internal bug. Tell me how many customers ever have a stable rise time of input voltage, with a monotonic…
