Part Number: ADS7138 Hello,
I am using an ADS7138 in autosequence mode, measuring all 8 channels every so often. The inputs are amplified thermocouple signals so the amplification factors before getting to the ADC are quite large and the circuits are…
Part Number: ADS7138-Q1 Hello, We are using the ADS7138-Q1 and have noticed in-rush current up to 2mA on AVDD and 10mA on DVDD at start-up.
Our test setup has AVDD and DVDD powered by two 3.3V power supplies with 1k resistor in series of the supply…

How to Use ADS7138 Autonomous Mode
After following the flowchart on page 25 of the datasheet, I noticed that when I set the threshold value lower than the…
Part Number: ADS7138 Other Parts Discussed in Thread: INA2191 Tool/software: Hi,
i am using (LT1790 max 5mA) for 4.096 reference of ADS7138. Since i also had INA2191 suitable for this line, i have added it on 4.096 reference.
I am little concerned…
Part Number: ADS7138-Q1 Other Parts Discussed in Thread: ADS7138 , TCA6408A , TCAL9538 , Hello Team,
For our project, we are using the ADS7138QRTERQ1 as a GPIO expander. In our design, AVDD is set to 3.3V and DVDD to 1.8V, and we require the GPIO signals…

Hi TI Team,
There are a few questions related to the 12-bit ADC converter (ADS7138):
How can we ensure that the ADC is set to either 12-bit or 16-bit mode? The documentation…
Part Number: ADS7138 Hi expert,
My customer is using ADS7138IRTER for a VR project as ADC and they are inputting the Hot swap IC(TPS259480) ILIM pin as an anlog input to it.
In some units they see that this voltage stays at high value which triggers…
