Part Number: ADS8902B By referring the datasheet of ADS8902B, it says Vref Input Range: 2.5-V to 5-V
For the minimum Vref 2.5V, it is understood that the input analog voltage of 2.5V will give the output as FFFFF Hex. so that the LSB is (2.5/2 20 ) = 2.…
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 dropped…
Part Number: ADS8902B I'd like to measure the amplitude of an amplitude-modulated 4V p-p 100kHz sine wave, at 18-20 bits resolution. I could
1. Demodulate it to a 2V p-p rectified sine wave, lowpass filter, amplify, and sample at 200ksps, or
2. Sample…
Part Number: ADS8902B Other Parts Discussed in Thread: THS4551 , ADS8695 , INA240 , TINA-TI , OPA189 , OPA388 Hi sir/madam,
By referring the datasheet of ADS8902B, the Vref is 2.5V to 5V.
If I choose 2.5V as reference, the full scale is 2.5V, so the output…
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:

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
Dale
Part Number: ADS8685 Other Parts Discussed in Thread: ADS8902B Hi TI team,
Can you please mention the minimum analog voltage(in mV or nV) changes is acceptable to this part? and what is the minimum voltage(in mV or nV) to start conversion(inclusive all…
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…
Part Number: ADS8900B Tool/software: Good morning,
For a project, I need to minimize connections to and from the ADS8900. As there is no requirement for a specific conversion start time, I wanted to connect CS_N and CONVST together as shown in the minimum…
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…
