Part Number: ADS8902B Other Parts Discussed in Thread: PGA280 , OPA320 , OPA625 Hi...
I have some problem with ADS8902B.
When I change the sampling frequency(through CONVST pin) from 10kHz to 100kHz/200kHz/250kHz, LDO output(DECAP pin) voltage is…
Hi Larry,
Welcome to the TI E2E Community!
The average of a rectified 4Vpp sine wave will be around 0.6V. Since you will amplify this in Option 1, this will likely result in the lowest overall total system noise. However, option 1 requires passing…
Hi keith
Please tell me that is it possible to change the gain of the analog front end shown in the figure 105 and figure 111 of ADS8902B. Or I should design a separate amplifier section before the analog front end? please suggest any application circuit…
Part Number: ADS8699 Other Parts Discussed in Thread: ADS8598S , ADS8598H , , ADS8900B , ADS8904B , ADS8902B Tool/software: Is there any other similar kind of adc with analog input range more than +/-6V and SPI compatible with 18bits or more precisio…
Part Number: ADS8920B Other Parts Discussed in Thread: ADS8902B , Hi there,
We are using the ADS8902B ADC in one of our designs and would like to get some clarification on the timing of SDO.
Below are screenshots from the ADS8920B datasheet:

Part Number: ADS8910B Other Parts Discussed in Thread: ADS8902B
The ADS891xB has a signal input range of 500kHz (1Msps/2) but the datasheet does not contain performance data for the input range. It has some information for f_in = 2kHz but no other data…
Hello Marco,
The default clock source on ADS8902B and ADS8900B is external SCLK, so writing internal registers is necessary to use internal clock as a mater mode. Thanks.
Best regards

Hello Venkatesh P17,
The minimum voltage depends on your full scale input range and ADC's resolution, there are four unipolar ranges for ADS8685 which is a single-end input 16-bit ADC, let's assume that you want to use 0~5.12V range, this means that…
Hi Cafain-san,
(1) The charge drawn from reference, for a given input voltage, is same for any conversion rate. When going from (b) to (c), you are changing the conversion rate i.e. the time over which this charge is delivered. Hence the average reference…
