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 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…
Part Number: ADS8684 Tool/software: Hi,
We use the ADS8684 in one of our designs. I studied the SBAA319 document (Extending Input Voltage Range and Understanding Associated Errors for ADC With Integrated Front End). There is a principal schematic shown…
Hi Vincent,
Ryan is on vacation now, so I will support you. The maximum SCLK frequency supported by ADS8688 is 17MHz. The command format is same for setting all ranges on all channels. Can you please let me know what code you got for the ranges/channels…
Part Number: ADS8684 Hello, My csutomer don't use AUX_IN/GND in their system and is asking me how to terminate them. I think just connecting AUX_IN and AUX_GND directly is enough, but is it also the best way for lower power consumption? They don't want…
