Thanks for your speedily reply! Here's some update that you might be interested.
I still want to use the SPI to interact with ADC and let McBSP to communicate with other peripherals.
After some modification with the FIFO register of SPI…
Part Number: ADS8353-Q1 Hi,
We are using ADS8353QPWRQ1 and is giving an external ADC reference voltage from an LDO through a buffer. The buffer output is fed to the ADC reference pin. The output broadband noise of the reference is filtered by a low-pass…
Part Number: ADS8353-Q1 Hi
We are doing the noise analysis of ADS8353QPWRQ1 in which we are trying to calculate the total noise of the ADC system. We are performing the analysis based on the TI-precision-labs video: https://training.ti.com/ti-precision…
Part Number: ADS8353-Q1 Other Parts Discussed in Thread: ADS8353 Hi,
We are using 32 CLK single SDO mode with 3.3V external reference voltage. We feed the ADC input from an opamp output (single-ended) through an RC filter (100ohms, 2.2nF). We use SCLK…
Part Number: ADS8353-Q1 Hello there,
about the acquisition time, the EC table says that the maximum acquisition time is tacq=33*tCLK-tconv= 33*50ns-730ns=920ns (when 20Mhz, dual SDO mode)
however, in figure 7-6 the tacq start at the end of tconv, ends…
Part Number: ADS8353-Q1
I have some troubles with the SPI interface of the ADS8353-Q1.
I have found out that I can correctly read and write the user programmable registers using SPI mode 1. In this case, the read data is shifted 1 bit left. The…
Part Number: ADS8353-Q1 hello there,
my test result of SPI SDO data latched edge is opposite with the datasheet.
my test shows that the SDO latch edge is the rising edge of SCLK.
however, the datasheet(figure 7-7. and table 10) say that the latch edge…
Part Number: ADS8353 Other Parts Discussed in Thread: ADS7853 Hi Expert ,
I want to confirm the ADS8353 SDO timing , base on the timing diagram in the page 41 of datasheet ,
The D15 is sent out from the No.17 falling edge , but in the description…
Part Number: ADS8353
I use the ADS8353 in Single SDO mode 32CLK, depending of the level of signal, I have digital noise.
An STM32 microcontroller is used for this, with a D flip flop to correct the phase shift of SDO output of ADS8353.
