Prodigy70points Other Parts Discussed in Thread:ADS1256 请教TI专家, 应该如何理解ADS1256数据手册上,表13和表14中数据关系,如表14中,30000sps对应的t19时间约0.23ms,这不是矛盾吗?
On the other hand, ADC designers are very clear on the difference between those terms and how it will affect application circuits. The common misunderstanding of the difference between latency and settling time can cause frustration when a system designer is in the throes of solving a signal-...
I am planning on having an op-amp buffer between the MUXOUT and the ADC IN pins. I am concerned whether I will still have settling errors even though I have the 10nF input capacitor at the input to the mux and also the op-amp buffer at the i...
This will cause the current sample to be corrupted by the previous analog input and resulting in cross-talk between the ADC channels. With the input settling time in mind, it is imperative to assure that the input settling time is less than the converter acquisition time t...
Part Number:ADS131E08 From figure 32 of the ADS131E08 datasheet I see that the time for this ADC to fully settle is 3 sample periods (i.e. 3 ms at 1kHz). How much will the ADC input settle in 1 or 2 sample periods if a step input occurs at the same time as...
1. The minimum time for the input signal multiplexing is given by PGA to ADC settling time tPGA_settling. 2. The rate of signal change within tPGA_settling must be small. So, how it looks with input signal change? I suppose for now that you measure voltages in range 1.5V..VDDA-1.5...

Other Parts Discussed in Thread:MUX506, I am using ADC ADS8588 for multiple channel acquisition with a front end mux MUX506 followed by a high slew rate op-amp AD744. We are finding that a settling time of 60us is required before the ADC accurately acquires the value. ...
ADC starts and the internal switch is open. The signal acquisition is critical but ADS8699 has an integrated ADC driver behind 2ndorder low pass filter which will execute this function in 5us acquisition time and meet this 18-bit ADC's settling requirement. The 15K...
