Part Number: ADS9120 Tool/software: Hello
We use the ADS9120 to read an analog signal,
we use it in the default mode, we do not write anything to it,
the pin 22 is left floating, SDI, and we are wondering if there is an integrated pullup or down into…
Part Number: ADS9120 Tool/software: Dear team,
Good day to you.
As for following materials, these MSLs are different regardress of the same materials.is it correct.
If yes, please tell us the reson. if no, could you tell me which is correct and revice…
Hi Jay,
Both ADS9120 and ADS9224 are SAR architecture, but there are differences. The ADS9120 uses a variation of SAR that is commonly used for higher resolution ADC's with resolution greater than 16b. This architecture has a limited input frequency…
Hello Harsh,
The ADS9120 requires a +1.8V supply for both AVDD and DVDD supplies, with an absolute maximum voltage of 2.1V. Based on your schematic, you are connecting AVDD to +5V and DVDD to +3.3V, which will cause permanent damage to the device.

Part Number: ADS9120 Hi Team,
My customer is working on one of the medical equipment and facing data corruption issue while using ADS9120 in the daisy chain mode (two ADC’s), below is the snapshot of the schematics for your reference:
And below is…
Part Number: ADS9120 I still have a problem capturing the Converted ADC data out. To avoid confusion, I do not write to any control register. Staying on SPI-00-S mode (instead of SPI-01 or 11 modes.) Upon power-up, firmware goes into an endless loop or…
Part Number: ADS9120 Hi team,
The first page of the data sheet lists the SPI clock as 200 MHz for regular and 45 MHz for enhanced. However, the Timing Requirements do not list them. Does this mean that each item in the Timing Requirements is for a method…
Part Number: ADS9120 Dear TI Community, I'm very sorry for the really basic question. Please teach me about ADS9120.
I designed circuit as shown on the next-figure. I think as follows: The ADC full scale is defined by VREFP / M. -> In this case, the…
Part Number: ADS9120 I want to make the following SPI data write to the ADS9120:
Write SDI_CNTL : Address= 0x14 , Data= 0x03
Is this a 2-byte SPI write, with the Address (0x14) as the LSB?
BUFFER[0] = 0x14 BUFFER[1] = 0x03
Or, the other way around…
Part Number: ADS9120 I need to use the standard SPI interface for the ADS9120, reading the converted data in 16 clock cycle. (not 20)
Table 5 lists # of clock cycles as 16, for optimal read frame.
However, figures 57 & 59 show 20 clocks (D0 to D19)…
