Part Number: ADS1158 We are moving from using the internal oscillator with external crystal to a clock generator for the ADS1158 ADC. Are there any particular points of interest to pay attention to when selecting a clock source? Does TI recommend a particular…
Hi Harsh Gola,
If AVDD is dropping to 4.7V, this is below the recommended operating conditions of the ADC (AVDD must be AVSS+4.75V, and I assume you are measuring AVDD with respect to AVSS). This could cause a wide range of issues within the ADC, since…
Part Number: ADS1158 Other Parts Discussed in Thread: ADS1278 In Auto scan mode in ADS1158, if we are utilizing all 16 channel, and lets say I am using 8usec time delay, no chopping, and 4 averages, with this config, let's say I am getting around 800…
Part Number: ADS1158 Hi,
I am using ADS1158 and on the same board a conditioning circuit is connected to the analog outputs MUXOUTP and MUXOUTN. The outputs of the conditioning circuit are connected to the analog inputs ADCINP and ADCINM.

Part Number: ADS1158 Hello,
I'm observing a rather ugly reflection using the ADS1158 IBIS model provided on TI website. No matter how I size the SST resistor or move closer to driver I don't see much of an improvement unless I significantly reduce the…

Part Number: ADS1158 Hi Team,
Can you please have a look at the following customer inquiry please? I will send you part of the schematic and register configuration if you reach-out to me via email.

Part Number: ADS1158 Hi
We would like to drive the ADS1158 FCLK with 5.2MHz.
Could you create a version of the following table with this clock instead of 16MHz?
Thanks,
Nir
Part Number: ADS1158 Hello,
The ADS1158 application in our circuit is to read voltages at the range of 0-5V
We are using external voltage reference of 4.95V instead of the example given 4.096V.
We are experiencing readings with increasing offset, where lowest…
Hi ZVI,
Since the REF5040 output voltage is with respect to the VREF ground, and you have the VREF ground = -2.5V, the 4.096V is relative to -2.5V (which is AVSS). This is almost exactly what is shown in the ADS1158 applications section (Figure 54), though…
