Part Number: ADS8684 Hi team,
I am evaluating the ADS8684 (ADS868x family) and have questions regarding the external reference configuration and its behavior during power-up.
Background:
External reference is applied to the REFIO pin.

Part Number: ADS8684 Other Parts Discussed in Thread: ADS8688 Hi,
At present in our application we are using ADS8684, 4 channel part.
Now we are trying to minimize the circuit and searching for alternate part in more number of channels. So please…
Part Number: ADS8684 Tool/software: Hi,
We set REFSEL to low, but REFIO only outputs 0.8V. RST/PD is high, so the chip is not in a reset state. Normally, when REFSEL is low, VREF_ADC should output 4.096V, right? What other reasons could cause this?…
Part Number: ADS8684 Other Parts Discussed in Thread: ADS8688 , ADS115H18 I am curious if this family (including ADS8688) is able to survive a -10V input.
From absolute max table, answer appears yes. I'm hoping to learn if you have concerns.
lastly…
Part Number: ADS8684A Hello, i've 10 board where the Vref of ADS8684A is 3.75 volt and not 4.096 volt. This voltage is on the pin 7-REFCAP and 5-REFIO. See schematic below. Can you suggest somethig about this issue ? Thanks
Part Number: ADS8684 Other Parts Discussed in Thread: DAC8775 Tool/software: Hi,
According to the ADS8684 datasheet, valid SDO width in the worst case is tHT_CKDO + tSU_DOCK = 10ns + 25ns = 35ns.
I understand that as the frequency of SCLK decreases…
Part Number: ADS8684 Other Parts Discussed in Thread: ISOM8110 Tool/software: Dear team,
we want to control the RST/PD pin via optocoupler. The fast reset within <100ns can be excluded then. We are talking about the >400ns power down as the opto pulse…

Hi,
I'm using the ads8684 adc with a Stm32f7 microcontroller and I can read the voltage with SPI communication on each channel (the values I get are correct)
but I cannot change the range…
Part Number: ADS8684 Tool/software: Using your ADS8684A4 channel AD acquisition chip, we are experiencing the following problems. Hardware using internal reference voltage, measured as 4.086V 1. Configuration range of 0-2.5 × VREF, when the input voltage…
