Hi Herbert,
Can you share a waveform of the issue seen at the SDO pin?
Below are the voltage requirements for the GPIO pins (see V_IH and V_IL).
The GPIO pins are set as inputs by default. The idea is that the status of the inputs are sent over SDO to…
Part Number: ADS7953-Q1 Tool/software: Hi Team,
can you check if there is a typo in the datasheet in Note A on page 40?
"A. A restriction on the source impedance exists. RSOURCE ≤ 100 Ω for the 1xREF 12-bit settling at 1 MSPS or RSOURCE ≤ 250 Ω…
Part Number: ADS7953 Tool/software: Dear Sir
we are facing the following problem: MXO pin is never equal to the selected Ch.
Given that in idle condition we see MXO at 3.3V
When i want to read the ADC, for instance CH4 (forced externally to GND), the…
Part Number: ADS7953 Tool/software: Hi, I have some questions about ADS7953 SPI sequnce.
I have set ADS7953 in Auto1 mode and if the CS falling edge aligns with the SCLK falling edge, or if SCLK is high when the CS falling edge occurs, does this conform…
Part Number: ADS7953 Tool/software: Hello Team,
We are currently using the ADS7953SDBTR and would like to utilize the GPIO feature of the ADC. Could you provide information on the source and sink current capabilities of the GPIO pins?
Additionally, since…
Part Number: TMS320F2812 Other Parts Discussed in Thread: ADS7953 , Tool/software: Hi team,
Would the ADS7953 be a suitable substitute for the internal ADC in the TMS320F2812? The customer's system update rate where they are using 12 channels is 4kHz.…
Part Number: ADS7953 Tool/software: Hello TI Team,
We have below queries related to the ADS7953 ADC.
CONF:1 - +VA - 3.3VDC, +VBD - 3.3VDC
If we change the VREF to 2XVREF, do we need to change the +VA (Analog power supply) to 5V from 3.3V while keeping…
Part Number: ADS7953
Tool/software:
Hello,
We are attempting to read 24 signals using a pair of ADS7953SBDBTR ADCs (U4 and U5) to read 24 signals (15 signals on on U4, 9 signals on U5).
The signals are sourced directly from 8 circuits, 3 signal outputs…
Part Number: ADS7953 Hi team,
could you help with below question for ADS7953?
is it necessary to use LDO to power VA/VBD/VREF? can we use the DCDC to power? and can we use one rail for these pins?
