  • RE: DAC161P997EVAL: Can't find software installer for this device

    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…

  • RE: DAC161S997EVM: Firmware

    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:

  • ADS1120: VQFN thermal pad layout

    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…

  • Where can I find SAT_LIB.schlib for the Altium design files in the example of RTD temperature transmitter TIDA-00095?

    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!

  • It's in the math: how to convert an ADC code to a voltage (part 2)

    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…

  • RE: 4-20mA Current Loop Receiver with MSP430.

    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…

  • RE: DAC161S997 Source Code

    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.

  • RE: DAC8760 interface with MSP430

    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…

  • RE: ADS1247 Output

    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:

    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…
