Part Number: REF2030 Hello,
The microcontroller we are using in our application has a requirement that the analog reference voltage, supplied by the REF2030, must be within 300 mV of its VCC rail, including during power-up. I would like to know if the…
Jerry:
We are debugging the circuit, the schematic says 1.5V because REF2030 is planned, when we found this nonlinear issue we tried REF2025 as well..
When we are using REF2030, the ADC reference is 3.0V and INA500C reference input is 1.5V
when REF2025…
Part Number: AM2634 Other Parts Discussed in Thread: REF2030 Tool/software: Hi, TI expert.
syscfg is always initializing the internal reference for for adc, How does AM2634's ADC use external reference sources?
Part Number: TPS7B4256-Q1 Other Parts Discussed in Thread: OPA206 , TPS7B84-Q1 , TPS7B86-Q1 , TPS7B91 , REF2030 Tool/software: Hi TI, can TPS7B4256 sink current? Probably not, but I just want to double check.
Part Number: REF2030 Other Parts Discussed in Thread: ADS7057 Hi,
I plan to use 5 ADS7057 ADC simultaneously. I supply the AVDD rails using a REF2030 voltage reference with 20mA source current capability. The REF2030 maximum recommended output capacitor…

Part Number: INA321 Other Parts Discussed in Thread: LMP7721 , REF2030 , , REF70 Hi, TI.
I designed a trans-impedance amplifier circuit using a LMP7721, INA321 and REF2030.
The INA321 was used to amplify the fluctuating voltage signal based on 1.5 volts. …
Hi Yunsik,
Ron is right, the OPA2353 is not very low noise at the lowest frequencies. The LMP7721 would give a noise improvement of about 2dB.
Keep in mind that U2 has a noise gain of up to 300p/4p7=64. Any noise given to the +input of U2 would be amplified…
Hello Ryan,
Thanks for your response.
Short answers to your questions:
- Yes, R1690 is installed,
- No, nothing else is loading the REF_OUT pin.
A bit more details:
We have the possibility to use either the internal reference provided by REF_OUT or an…
