Part Number: ADS7870 Hai Sir,
My End application is - Controlling & Analog outputs driving.
As per the customer suggestion we are going to use the ADS7870 for receiving the Analog Inputs.
As per the attached image pls verify the design and let me…
Part Number: ADS7870 We received the part with old date code 2016 . How much years old DC it can be used? As per quality procedure of avalon we cant use with DC less than 3 years We need TI written confirmation for old DC confirmation on the shelf li…
Hi
Thanks for your answer, the delayed response for my part is due to summer vacation.
We have been using pin 28 as the connection for the external reference. The VDD that are being used are 3.3 Volts, witch is higher that the reference voltage of 3…
Part Number: ADS7870 Good day!
I have a question regarding differences between ADS7870EA and ADS7870EAG4.
Through the datasheet, I can not find any differences between them. I would like to know ADS7870EA can cover ADS7870EAG4 or not.
Because ADS7870EAG4…
Other Parts Discussed in Thread: TLC2543 , ADS7870 I am looking into two different development boards which uses TLC2543 and ADS7870 for A to D conversion. From comparing both IC's I have found out that the resolution of both is 12 bit. However, development…
Hello,
I am using an ADS7870EVM board in conjunction with an arduino uno (ATMEGA328), and am in the process of writing a library for easy use of this ADC. I am using the arduino framework, but have moved beyond functions like digitalWrite etc because…
Other Parts Discussed in Thread: ADS7870 Hi,
I'm trying to communicate between the ADS7870 and the ST microcontroller STM32F4 Discovery evaluation board. I'm using IAR and at the moment I'm just trying to read register 31 from the ADC but with no luck…
Hi Saeed,
There are many options to design the thermistor circuit, and convert the voltage to 4-20mA current loop. I need to have clear direction how you want to proceed.
Your thermistor application is operating such a wide temperature range from ~700kΩ…
Other Parts Discussed in Thread: ADS7870 I recently purchased a ADS7870 Eval Board. I wanted to know if there is a
schematic showing a connection to a micro controller unit.
Melissa,
It's certainly possible to use the ADS7870 as it has the option of using 4 differential inputs with the mux. However, I think the ADS7870 is a bit more complicated than what you need for the application. It will also have a bit more error in…
