  • TIDA-01525: same request(For the higher voltage with TIDA-01525)

    Resolved
    Part Number: TIDA-01525 Other Parts Discussed in Thread: DAC80508 Hi TI, I have the same request. The current range of TIDA-01525 is satisfactory, but I want to apply PVDD at least 15V (because the voltage of the load is high) Can you give me a guide design…

  • TIDA-01525: Schematic Files

    TI Thinks Resolved
    Part Number: TIDA-01525 The TIDA-01525 device is useful for me, but I would like to modify the schematic to change the amplifiers & transistors to handle higher voltages. Do you have an editable version of the schematic in .SchDoc format (or other schematic…

  • TIDA-01525: TIDA-01525

    Resolved
    Part Number: TIDA-01525 Other Parts Discussed in Thread: TLV9061 Hello, Can I set the voltage to 400 Volts for this circuit. Of course, I will use the flyback converter for 400 volt DC. I need: 0-200mA adjustable current source for 400 Volts.

  • RE: need to find a suitable part

    Hi Cooper, To my knowledge, TI does not have a device that can output current of that magnitude. Generally, we recommend a precision DAC with a high-side or low-side current source. https://www.ti.com/tool/TIDA-01525 Take a look at this reference design…

  • RE: Precision current source

    Resolved
    Hmmm yeah, it doesnt't seem that those IC's are able to provide specific current. I'll stick to that TIDA-01525 design. Thanks for your help!

  • RE: Programmable current source

    Hi Arelone and Kai, The biggest issue you will find in the bandwidth. 500kHz is difficult because 1Msample is pretty much the max on our fastest devices. You can look at a Howland current pump for the output or a current mirror as a high-side current…

  • DAC80508: DAC80508 application in TIDA01525

    TI Thinks Resolved
    Part Number: DAC80508 Dear team, Customer found TIDA01525 could be apply to their end application, but they need the current to 300mA. I see from the guide that the current is set by reference voltage and several resistor, so could we modify this reference…
