  • RE: INA592: 4-20mA current source

    HI Shibin, As Kai has mentioned, on the current transmitter application, the main issue with the Howland Current source configuration is that could be sensitive to capacitive/inductive load and will likely become unstable while driving a long cable. There…

  • DAC8760: VOUT Shorting to GND

    TI Thinks Resolved
    Part Number: DAC8760 Other Parts Discussed in Thread: TIPD119 When DAC8760's VOUT pin short to GND, what happens? In the d/s, it says that the current will be clamped 30mA, correct? If the short fault event is kept for a long time, the package thermal…

  • RE: ISO7741: Separating GND using the Isolation solution

    Resolved
    Hi David, The primary reason for isolating in the digital domain is that it is relatively easy to isolate a digital signal and reproduce it accurately without any issues than an analog signal directly. Isolating an analog channel directly will pose many…

  • RE: DAC7760: DAC7760 overheating issue

    Hi Rohidas, What is the condition of the output when the device is overheating? Does the device get damaged? The thermal pad should be connected to AVSS as your schematic indicates. I also noticed that you are tying Vout and Iout together. When tying…

  • DAC7760: Connect to Launchxl-F28377S

    Part Number: DAC7760 Other Parts Discussed in Thread: ADS5560 , TIPD119 , DAC8760 , LMT87 I'm preparing the analog out test based on Slau519 and try to use existed Launchxl-F28377S but its most of pins have been occupied. Do you have experiences to handle…

  • RE: DAC7760 Unipolar configuration schematic.

    Resolved
    Nikita, I believe you are correct that there isn't any schematic / reference design that is exactly like what you're asking for. That said, I think TIPD119 comes pretty close. The only modification you would need to make in order to make TIPD119…

  • RE: Looking for part/reference design for a 4-20mA driver

    Resolved
    Hi John, Take a look at the DAC8760, or a DAC + XTR combination like the design shown in TIPD155 . We also have a few reference designs featuring the DAC8760. Take a look at TIPD119 and TIPD153 .

  • RE: DAC8760 load specifications and design considerations

    Resolved
    Anastasios, Anastasios Moschos said: 1) Are there any limitations concerning the load impedance? Will it work ok for my application? As far as I saw the datasheet specifications are based on 300 Ohm loads only. Could you provide some data for the current…
