Part Number: ADS1257 Tool/software: Looking to use the typical application circuit ( Fig 65 ) to sample a 4-20mA pressure transducer in an industrial environment.
The typical application samples at 10SPS for 50/60hz rejection. In the case where a higher…
Part Number: ADS1257 Hello.
I will repost in English.
ADS1257 is used for differential measurement with 2000SPS, PGA = 2, ACAL ENABLE, BUF Disabled settings.
2.4V is input to AIN1 and REF from the high precision reference power supply.
Input 2.4V to…
Hi Chris Hall,
Thank you very much for your detailed reply. I would like to follow up with you regarding the previous responses.
"If you synchronize all three ADS1257's then you would only need to monitor one /DRDY signal."
Can my sync…
Sorry,
I mean the crystal oscillator (the one similar to that in your provided links). A crystal oscillator has 4 pads. For a microcontroller, I usually connect pad 1 to OC1 and Pad 3 to OC2 of the microcontroller. But the ADS1257 only has one pin CLKIN…
Part Number: ADS1257 Hi,
Let me ask you some basic questions about ADS1257 as below.
Q1) INL specifications
Following is a part of System performace table (data sheet page 7)
Q1-1) About INL, the value is only "+", there is no "-" value, +3ppm(typ)/…
Part Number: ADS1257 Hi,
Let me ask you a question about "Single cycle" .
There is a description on the datasheet as below. (Red)
Does this mean "Single-Shot Mode", right?
I do not understand why is "<= 1000SPS".
Will…
Part Number: ADS1257 Other Parts Discussed in Thread: ADS124S08 I would like to ask you about very basic question, "Single-Cycle Settled Conversions"?
Basically, a delta-sigma A/D is used as "continuous" conversion due to internal digital filter…

Please review this schematic
Notes:
1) ADS1257 does not allow to place beads at power input so 4 ldo ics were placed
2) General comments, design suggestions
