Roberto,
I don't know if we have the original source for the DAC161S997. However, there are several example TI designs that use the DAC161S997 as a loop controller and have some firmware written for some of our MSP430 devices. You can find these designs…
Other Parts Discussed in Thread: TIDA-00095 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!

CSC,
There isn't much available for example code for the DAC161S997. However, if you go to the TI design for TIDA-0095, there is a zip file for some of the firmware using the MSP430 and DAC161xxxx devices. In the zip file, you can find the DAC161.h…
Steven,
There are many devices in the DAC product line that can be used to generate a 4-20mA loop. For an example you can look at this TI Analog Engineer's Circuit that describes a loop-powered 4-20mA transmitter circuit:

Waseda,
I'm not entirely sure what you're asking, but I think maybe a diagram from the datasheet might answer your question.
The DAC161S997 only does the 4-20mA current loop drive, it doesn't communicate with any sensors. From the diagram you…
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:

Part Number: ADS1120 Other Parts Discussed in Thread: TIDA-00095 , 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…
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.

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…
