  • RE: BUF802: BUF802 's Bode test result

    Well Jimmy, you might request the set up and equipment used in the datasheet plots.

  • BUF802: BUF802

    Part Number: BUF802 Hi: I measured the input impedance of the BUF802 reference circuit downloaded at this site SBOMBQ8D.TSC, I took out the 50 Ohms input resistor and changed R source until I got half of the input voltage and I got 115Kohms not 1Mohms…

  • BUF802: Pole at the input of IN_AUX

    Resolved
    Part Number: BUF802 Other Parts Discussed in Thread: OPA828 , OPA140 , TINA-TI In the reference designs for the BUF802 in CL mode, there is a RC filter between the output of the precision amplifier and the IN_AUX pin of the BUF802. In the datasheet it is…

  • RE: BUF802: BUF802 NC pin qestion

    Hello Jimmy, We have confirmed that the NC pins are not connected internally; therefore, these pins are electrically isolated from the die. Kai is correct, they are connected to neighboring pins to ease the layout. Thank you, Sima

  • RE: BUF802: Input Clamp diode connected to CLH, not VS+. Why?

    Resolved
    Thanks for the clarification Sima. Understood on the NJFET biasing. That is a shame as we really wanted to use the clamping in the BUF802, but also need to allow full +/-5V input swing without distortion on the capacitive divider. So will look at clamping…

  • BUF802RGTEVM: BUF802 reference design

    TI Thinks Resolved
    Part Number: BUF802RGTEVM Hi I would like to know how to connect with Pin 9/13/16. -Because NC for those pins in datasheet -They still have connection with VEE or VCC in EVB design. Please let us know how to connect with pin 9/13/16 for design.

  • BUF802: Missing pins in SPICE model?

    Part Number: BUF802 Other Parts Discussed in Thread: BUF602 Hi. I am confused a bit by the PSPICE model for this part; I am attempting to use the model in another SPICE simulation tool and the model appears to not have any definition for 2 pins on the…

  • OPA859: BUF802 CST MWS

    TI Thinks Resolved
    Part Number: OPA859 Other Parts Discussed in Thread: TINA-TI , , BUF802 Hello, I am trying to include the OPA859 amplifier into a 3D EM Co-simulation with CST MWS for an integrated antenna and circuit simulation. I am unable to import the TINA-TI SPICE…

  • BUF802: Spice Model error

    TI Thinks Resolved
    Part Number: BUF802 Other Parts Discussed in Thread: TINA-TI , After loading the "BUF802 TINA-TI Reference Model" from the website into TINA 9, and trying to run the analysis (DC or AC) of the circuit, I get an error related to the Model Is there…

  • OPA140: One free sample request for BUF802 EVM

    Part Number: OPA140 Other Parts Discussed in Thread: BUF802 Hello, My customer has purchased BUF802 EVM where all the parts are all expected to be populated, but it was a bare board. I got reply in E2E that it comes with IC populated, so I asked BUF802…
