Part Number: ADS7953
Hi Team,
Posting on behalf of our customer.
In our design, we are using the ADS7953SBRHBR ADC with a reference voltage of 2.5 V. The analog input is 3.3 V, and the digital input is 2.5 V. Both the 3.3 V and 2.5 V rails are…
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-Q1 Other Parts Discussed in Thread: ADS7953
Hi, the datasheet specifies that VA and VBD must be “well regulated”, but it does not provide quantitative limits for ripple or noise, which makes it difficult to size the power‑supply…
Part Number: ADS7953-Q1 Tool/software: Dear Expect:
Current problems:
1. There are two AD conversion chips on the board, one of which has four pins of GPIO0~GPIO3 suspended in the air and can read data normally, but there is a small induction waveform…
Part Number: ADS7953 Hi,
I need to design an external RC filter for the ADS7953 ADC.To calaculate V_step,I need the sampling capacitor value of the ADS7953 IC.
I went through the datasheet but couldn't find this information.
Part Number: ADS7953-Q1 Other Parts Discussed in Thread: ADS7953 , I'm currently desinging an external ADC with HV (~100V <1mA laod) MOSFET control capabilities. The ADS7953QDBTRQ1 is exaclty what I need but the GPIO data is kinda ambigious. Also, I compared…

Tool/software:
Is there anyone I can email a schematic of the ADS7953SBDBT for design verification before I do a board spin? Pretty simple 1 page design but would like to be sure everything looks good.
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?
Part Number: ADS7953 Tool/software: Looking to use the ADS7953SBDBT and interface it with USB. What's the easiest way to do that and how big of a firmware lift is it? Had been considering USB to SPI bridge using the FT2232H-56Q-TRAY, but figured TI has…
