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 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 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…

Hello,
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,
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 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-Q1 Other Parts Discussed in Thread: TINA-TI Hai,
How do we calculate input impedance for Analog Input Output pins of ADS8353QPWRQ1?
Part Number: ADS8353-Q1 Other Parts Discussed in Thread: OPA2320-Q1 , REF34-Q1 , ADS8353 Hello, I am using the example external voltage reference that implements the REF34-Q1 with the OPA2320-Q1 to supply a reference voltage to REFIO_A and REFIO_B. However…
Part Number: ADS8353-Q1 Hi,
The datasheet describes the internal reference voltage(2.5V). Can external reference voltage be used,
If so, can external reference voltage be up to 5V?
Thanks!
Hello Walteros,
Good to know that potential divider resistors are in between High Voltage Positive/Negative lines to Chassis Ground.
I recommend to use a precision ADC (ADS8353-Q1) to measure the ISO_POS and ISO_NEG and transfer digital data across isolation…
