Part Number: REF3450 Hi Team,
Does turn on time have dependency of temperature? This is because our customer check the Vout turn on time behavior of across temperature. They can see like figure as below. the red line is on datasheet. I add the blue line…
Part Number: REF3450 Hi,
Now I'm referring the reference circuit Fig 2 in page 22 of following document that configure current reference with voltage reference IC, FET and buffer amp.

But now I'm considering…
Part Number: ADS1220 Other Parts Discussed in Thread: REF5050 , REF3450 , ADS1118 Hello i need help for using the vref and read 0 to 5 volts with ads 1220 i am trying to search and find the way to do it but i cant get any clue im using the arduino nano and…
Takahashi-san,
We currently don't have any products with such low long term drift. Depending on the calibration interval and the temperature range of operation one of the following products may be suitable: REF7025 (in Ceramic) about to release https…
Part Number: REF34-Q1 Hello,
How will the long-term stability of REF3425-Q1 and REF3450-Q1 look like over 15 to 20 years? The data sheet specifies only values over 1,000 or 2,000 hours.
Best regards, Shinichi Yokota
Hi Marcoo Z,
Thanks for your advice.
I understood that "only a max of 0.5V" refers to the case with REF3450.
For example, when using REF3430 or REF3440, the allowable voltage drop is 0.7V, isn't it?
Why is the former not 2.5V and the latter…
Part Number: LM4041-N Other Parts Discussed in Thread: LM4040-N , LM4050-N , REF3450 I am looking for more stable voltage regulater for temperature.
I am using LM4041DIM3-ADJ for 5V output from 8V input .between -20degC to +80degC. the datasheet said temperature…
Hi,
Below are two scope shots of the input and output of the REF3450. Channel 1 (yellow) is the input voltage, and channel 2 (blue) is the vref output.
The first scope shot is a function generator input with a 10V /1ms slew rate. As you can see here the…
Part Number: ADS1220 Other Parts Discussed in Thread: REF3450 , Hi,
we want to measure four single-ended channels (voltage range 0 to 5V) with a gain of one and AVDD as reference. We will supply AVDD directly from a 5V reference chip (e.g. REF3450), DVDD…
Part Number: LM4030 Other Parts Discussed in Thread: REF3450 LM4030B is a "ultra-precision" shunt reference (1% and 20ppm/°C) up to 30mA.
Is there an (easy) application to build a (ultra-precision) 5V reference with more current capability…
