  • DAC161S997: unable to control the loop current through DAC161S997 IC

    Part Number: DAC161S997 Other Parts Discussed in Thread: LM2936 , I developed a 4-20 mA, loop powered transmitter circuit using DAC161S997. The loop is powered using LM2936, which is generating 3.3Volts. i am able to set/control current upto 6 mA, after…

  • DAC161S997: Query regarding loop error generation.

    Part Number: DAC161S997 Hi Team, I'm using dac161s997 Ic for 4-20mA output generation. I want to use the ERRB PIN for showing "loop open" message on my device but the ERRB PIN always stays pulled down whether the loop is closed or open. …

  • DAC161S997: Initial Code Help

    Part Number: DAC161S997 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…

    TI Thinks Resolved
    Part Number: DAC161S997 Hi, What is the DAC161S997 MTTF? Can you give an estimate? Thank you Best regards

  • DAC161S997: adjust slew rate control at which the output current changes

    TI Thinks Resolved
    Part Number: DAC161S997 Other Parts Discussed in Thread: DAC8771 , DAC8750 , DAC8775 , DAC8760 Hello, We’ve implemented DAC161S997 to our new prototype and already tested for 4-20mA output. We would like to adjust slew rate control by software or…

  • DAC161S997: DAC161S997 Self-Powered with DS8500 HART modem

    Part Number: DAC161S997 Hi, We have a self-powered DAC161S997 design connected to DS8500 HART modem. We facing problem we think it has with FSK-out filtering. I'm being confused between the DAC161S997 datasheet and the dac161s997evm schematic regarding…

  • DAC161S997: Loop Error

    Part Number: DAC161S997 Hello, We are using DAC161S997 as a self-powered transmitter. We have followed the application schematic provided in the datasheet and in this forum. We are using 24V as loop power for 4-20mA output. The device goes into loop error…

  • DAC161S997: DAC 1612997 power loop

    TI Thinks Resolved
    Part Number: DAC161S997 Other Parts Discussed in Thread: , TPS61045 HI sir I use the DAC1612997 For 4-20mA output is ok, when power loop is from external power supply but if i want to use the USB power to supply the 24 v, did you have any suggestion…

  • DAC161S997: Loop Error occurs at large DAC outputsignal jumps

    Part Number: DAC161S997 Hi, We use the DAC161S997 for our 4 - 20mA pressure transmitter. Now we have the problem, that if we use a high load resistor (510R) and a supply voltage of 24V, The DAC goes straight to loop error when we send as first DAC setting…

  • DAC161S997: Status register readback issue

    Part Number: DAC161S997 Hi.. One of my customer is using DAC161S997 for their Industrial product where they are controlling the motor speed using 4 to 20mA input. They are using 24V as Loop power supply for 4 to 20mA output & they also use 3.3V as external…
