  • RE: REF2025: 1/f Noise Reduction

    Resolved
    The reason I did not recommend the LM4140 is because it only works from 0C to 70C. The ADS1271 is usable in a longer temp range. If this ADC is only going to have a ambient temperature between 0C to 70C, you can use LM4140. I prefer the REF50 due to…

  • RE: REF5010: Noise Performance

    Hi Ole, The REF50 family of spice model has accurate wide band noise. Yes it does include the effect of the capacitor on pin 5.

  • RE: REF5050: warm up time required?

    Hi Andrew, The REF50 does not require a warmup time. Is there an issue the customer is experiencing?

  • RE: REF5025A-Q1: long term stability

    Hi Andrew, Use the EC table for 10 ppm/C for SOIC8. The REF50 used to be offered in MSSOP and that package had a 5ppm/C LTD after 1khr. The datasheet needs to be updated to reflect the current LTD.

  • LM4140: operation below zero temperature

    TI Thinks Resolved
    Part Number: LM4140 Other Parts Discussed in Thread: REF50 Is there any data how LM4140 performs under 0 C? The exact temperature I'm interested in is -15C. Thanks! --Juha

  • RE: REF5045: In REF5045's data sheet, Vout is missing

    Wen, You're right, REF5045 is not mentioned for some reason. I'll look into this offline, but meanwhile, please consult the REF50-Q1 datasheet , where you can see that the typical will be 4.5 V as you mentioned. Thanks, Abhinav.

  • ADS7950: REF pin of ADS79xx

    TI Thinks Resolved
    Part Number: ADS7950 Other Parts Discussed in Thread: REF50 Hi, I have some question about REF of ADS79xx series. I would like to confirm how to select an external reference voltage device. ①Does the REF pin need a device that can drive more than ±10mA…

  • Does TI have a voltage reference chip with an accuracy outperforming one out of 10,000?

    TI Thinks Resolved
    Other Parts Discussed in Thread: REF50 Hi Team, Customer need a voltage reference with high accuracy and good stability. Does TI have a voltage reference chip with an accuracy outperforming one out of 10,000? Thanks.

  • RE: REF5020: -Voltage adjustment in TRIM pin (-10mV)

    Hi Vairavan, I would suggest to use TINA-TI to solve the op amp equation or else look into Howland current source for something similar.. I cannot help you with manually solving it. I also cannot provide the values of R1 and R2 which are missing in…
