ADS1014-Q1: power consumption based on 125C and 105C

Ann_Lien

Part Number: ADS1014-Q1

Tool/software:

Hello expert,

My customer is asking for the power consumption in high temperature 125C. Do you have test data for this power consumption. If you don't have this parameter, do you have experience that how high for the ADS1014-Q1 power consumption would be in high temp environment? Below table only shows typ. value and we would like to know the maximum value @ 125C. If there is no 125C data, 105C data is also acceptable for them. Thank you.

Best regards,

Ann Lien

Hi Ann Lien,

I'll ask if there is any information on this available and will get back to you.

Best Regards,

Hello Angel,

Please check that customer is using FSR=4.096V and also double check if FSR value will cause power consumption different. Customer need to know the answer by this week, please kindly help on this case soon. Thank you so much!

Best regards,

Ann Lien

Hi Ann Lien,

We only have data available at the test conditions stated in the data sheet.

Note that maximum and minimum specifications apply from TA = –40°C to +125°C, so at +125°C the current consumption will not exceed the max value stated in the data sheet.

Having a different FSR setting does not affect the power consumption, you can expect the same values at other FSR settings as the FSR = 2.048V stated in the data sheet.

Best Regards,

Angel

The max current consumption (including temperature range up to 125C) is 300uA.

You can multiply this value times the VDD voltage value to get the max power dissipation of the device. At 5V, this would be 1.5mW. This is the max power consumption of the device, across all temperatures. Actual value will typically be lower than this.

Because of the holidays, TI E2E™ design support forum responses will be delayed from Dec. 25 through Jan. 2. Thank you for your patience.
