Part Number: ADS1258-EP Other Parts Discussed in Thread: ADS1258 , REF2025 , BUF634
Hello,
1. We want to measure 16 sensors single ended with the ADS1258. The sensors are configured as a quarter bridge with the circuit taken from the TI example below. R10…
Part Number: REF2025 Hello,
We are using the REF2025 in a test fixture that gets temperature cycled as part of the test. The test fixture voltage reference is measured with a high precision DMM, then the fixture is removed and temperature cycled some…
Other Parts Discussed in Thread: REF2025 , LM4132
Hi all Would you mind if we ask REF2025 and LM4132 ? About initial accuracy, as time of energization passes, does this initial accuracy change? (According to passage of energization time, does accurancy value change…
Hi,
I would like to replace LT1790-2.5 on a pcb already designed.
I think I have two options:
-REF2025 but I need to know if it works with Vbias(pin 1) connected to gnd(because pin 1 in LT is gnd) and Enable(pin 3) floating.
-REF3225 if it works with…
Hi Neguse,
Yes, the REF35125 is currently in preproduction.
If you need it sooner than that, please look at using the REF2025 or REF3312 and follow the same circuit as in the REF35 data sheet.
With a shunt reference, you can use the TLV431B and flip the…
Hi Gama,
I am searching for clues or explanations.
1. Changes in Rg resistors from 249Ω to 1k Ω does not change Vout, this implies that Vout's voltage may not related to input for some unknown reasons, which it does not make much sense. Can…
Thanks for the update. Let us know what you find out what the customer includes in the 0.1% accuracy - over temp, input voltage, output current, time etc., and any specifics about the automotive application you can share. Another alternative is the REF2025…
Part Number: ADS131M08 Other Parts Discussed in Thread: REF2025 Hi Team,
Could you help to share the input impedance of ADS131M08`s REFIN pin@32kHz data rate?
Does the REFIN pin have a internal BUFFER?
Can we use resistor divider to offer reference for…
Part Number: REF3312 Other Parts Discussed in Thread: REF2025 Hello team,
I'm looking for a precise voltage reference which has performances below. - Output: 1.2V or 1.25V - Accuracy: <0.2% - Temp drift: <7ppm/C - Drive capability: 10mA< sink&so…
