Hello,
For lab check of part: ADS1118 Ultrasmall, Low-Power, SPI-Compatible, 16-Bit Analog-to-Digital Converter with Internal Reference and Temperature Sensor
I will appreciate your answers for the following question:
1. The component ("part - ADS1118") is cold junction compensation - should the component be kept at constant temperature as possible ? e.g - connecting component case top to heatsink via thermal pad
2. If the component is not kept at constant temperature - will it show false/non physical temperatures values ?
3. Do you have any thermal experiment reports of this component, tested when implemented on PCB
4. In the DS at table 4: 14-Bit Temperature Data Format, as per my understanding the showen temperature is interpolation between two values:
e.g - if measured 7°C will it show 5°C or 10°C ?
5. Any specific recommendations when the component is implemented in rapid changing environment - components ambient temperature is changed very fast
Hope to hear from you soon,
Igor
