Part Number: ADS8698 Other Parts Discussed in Thread: ADS8689 Tool/software: Hi,
If the RST/PD pin on an ADS8698 is connected to connected to AVDD (5V) through 10kΩ pull-up resistor, and DVDD is set to 3.3V, is there risk to damage/operation of the …
Hi Ernist,
Unfortunately I don't have code for you. The conversion time is fixed by an internal clock - the acquisition (sampling) time has a minimum value, but there is no MAX value - basically the ADS8698 goes back into acquisition mode as soon…
Part Number: ADS8698 I have the 8-Channel ADC with the full part number: ADS8698 32TQ4 ADYP which shows some deviations from the datasheet.
I get data out of 4 channels and the AUX.
a. Data out on channel address range is consistent with 4 channel (C000h…
Hi Aswin,
Does your the SPI bus in your CPU have a push-pull or open-drain output? A timing plot for SDO,SCLK,SDI and /CS captured with an oscilloscope will be very helpful to address the issue.
Were those resistors (R173/R237/R171/R234) installed? ADS8698…
Part Number: ADS8698 Greetings,
I encountered two problems using the ADS8698.
Firstly, the sampled value only changes once in about 1 or 2 seconds, even though I'm polling the specific channel many times per second. For now, only one channel is being used…
Part Number: ADS8698 Dear colleague,
Our customer instrument is using ADS8698, ADS8698 and MCU are in different PCB, two boards are connected by a conductive slip ring.
Recently, they have done the EMC test for this instrument, ADS8698 is normal in EMC…
Part Number: ADS8698 Adc saturation problem.
when i am using the stable power supply i m getting the correct output from adc on spi bus.But whenever i am using the power supply having slow settling time or i can say unstable power supply....then i am…
Part Number: ADS8698 The ADS869x datasheet specifies 25 ns minimum for "Setup time: SDO data valid to SCLK falling." It would be better for TI to spec an output pin with max propagation delay (clock edge to data valid). Is 25 ns specified assuming it…
Part Number: ADS8698 Other Parts Discussed in Thread: ADS8694 , My ADS8694 is not responding on SPI, similiar to this question:
The platform is Raspberry PI 4, and on this platform, the SPI writes are per byte, and the clock stretches in between the bytes…
