Other Parts Discussed in Thread: DAC161S997
Hello, it is possible to have the drivers or the protocol implemented on the serial interface of the EVM to interface it with our PC program?
Thanks

Hello E2E Experts,
Good day.
I am a coorporating professor with a small senior project team that is striving to utilize your 16-Bit precision DAC. We have this wired and are testing the SPI, but after many hours we are still not…
Hi Team,
Our customer is looking for a 4-20mA looped powered chip. It will be similar to the XTR117, but needs to have digital input like SPI or I2C instead of a voltage input. Does a…
Hello every one
I am new here.
Could you please suggest us how to start for reading SPI sensor to 4-20ma?
1. Can I use this DAC for reading SPI sensor to 4-20ma?
2. If 1.…
第11部では、電源ノイズについて取り上げ、ノイズが多い電源になる原因や、A/Dコンバータ(ADC)に与える影響などにつ��て述べました。また、ノイズ除去において電源の影響の度合いを測定する方法として、電源除去(PSR)を紹介し、電源ノイズが各種のADC電源に与える影響を分析しました。
最終回となる第12部では、ADS127L01評価モジュール(EVM…
Hi,
The EVM for the DAC161P997 has its own software, found on the EVM landing page:http://www.ti.com/tool/DAC161P997EVAL#0
Other than the software for this specific evm, there is no software related to the DAC161P997. The C and H files you found are for…
Hi Gary,
I do not believe the EVM firmware is available but we have a couple of reference designs with DAC161S997 + MSP430 that include the firmware:

Dear Experts,
Is there any further instructions how to design layout for ADS1120 thermal pad and ground pins? According to datasheet p.4 thermal pad should be left unconnected or be connected…
I downloaded the design file (Altium Design) of RTD temperature transmitter, but didn't find the lib file SAT_LIB.schlib in it. Do anyone know where to download this lib file?
Thanks!

In part 1 of this series, I explained how you can calculate the input voltage to an analog-to-digital converter (ADC) by multiplying the ADC’s output code by the least-significant bit (LSB) size using Equation 1:
To calculate the ADC’s LSB size…
Kummi,
Just to support what Dennis mentioned, yes you can very easily implement a 4-20mA receiver with an MSP430. Dennis' suggested method of designing a shunt resistor is the industry standard as well.
We usually do not see MSP430s being used this…
Hi Tim,
In the TIDA-00095 Ref Design: ( www.ti.com/tool/TIDA-00095 ), there is source code for the MSP430 and DAC161xxxx devices: TIDA-00095 Firmware .
DAC161.h and DAC161.c files in the .zip file.

Mitesh,
I'm not entirely sure what you need help with. Interfacing with the DAC8760? Choosing the correct MSP430 for a HART application? Creating the SW stack for the HART protocol?
A HART field transmitter has four basic sections to it: a sensor…
Hi Saumitra,
I think your problem is in how you are determining and using the slope. I think it would be best if you looked through this document:
http://www.ti.com/tool/TIDA-00095
This TI Designs is a temperature transmitter design using the ADS1220.
…Hi Orlando,
You bring up some very good thoughts about this process. As you have already discovered, there are accuracies relative to the sensor, and repeatability of the sensor that are not taken into account. Component and component drift must be considered…
Dear Bob and all the Precision Data Converters team,
First I would like to thank you because you are providing vital support to our projects. Thank you for your answers.
Then I would like to start asking questions once more.
My goal is to create a 0.05…
Andrea,
A colleague pointed out there are a couple of ADS1220 code examples:
First for an ADS1220 project:
http://www.ti.com/tool/TIDA-00095
And other code found in our wiki:
http://www.ti.com/lit/zip/sbac227
While the register space may not be exactly…
