  • AFE20408: AFE20408 vs AMC7834 DAC current capacity for GaN Power amplifier

    TI Thinks Resolved
    Part Number: AFE20408 Other Parts Discussed in Thread: AMC7834 , , AFE10004 Tool/software: Hi, AMC7834 has +/- 10mA (source/sink) typical DAC current capacity whereas AFE20408 has +/-90mA typical DAC current capacity. My Doherty GaN amplifier needs…

  • AFE20408: About AFE20408 PCB macro and circuit symbol .

    TI Thinks Resolved
    Part Number: AFE20408 Tool/software: I'm looking for AFE20408 PCB macro and symbol (KiCAD 6+) but it seems no data in Ultra Librarian. Ultra Librarian for TI H ow to request making AFE20408 PCB macros and symbols? Thank you.

  • AFE20408: GaN LDMOS biasing with AFE20408

    TI Thinks Resolved
    Part Number: AFE20408 Tool/software: I was studying the IC AFE20408 and I found it suitable for my application. However, I can see that the Evaluation version has used NMOS FDC6305N for the VDD PAON switch. My application requires a drain current of at…

  • AFE20408: Power supply collapse - power down timing

    Part Number: AFE20408 Tool/software: A register configuration scheme that can satisfy the off-sequence of a GaN power amplifier using the automatic power-down function of the afe20408 GaN bias controller chip during a sudden power outage. The timing…

  • AFE20408: Unused Outputs

    Part Number: AFE20408 Tool/software: I am working on a design using the AFE20408 to control two GaN amplifiers. The first amplifier gate will be controlled by OUTA0 (DACA0 and DACA1). The gate of the second amplifier will be controlled by OUTB0 (DACB0…

  • AFE20408: PAON

    TI Thinks Resolved
    Part Number: AFE20408 Tool/software: Should we use PAON in open drain mode only using external nmos circuit. Which mode is suggested for AFE20408 PAON pin for GaN drain control?

  • AFE20408: Enabling PAON disables dac outputs despite all alarms being disabled and dacs set to be on

    Part Number: AFE20408 Tool/software: Currently using the evaluation kit with the following configuration: VCCA = VCCB = GND VSSA = VSSB = -4V VDD = 5V VIO = 3.3V the ftdi bridge is fully disconnected from all jumpers. I am using my own micro…

  • AFE20408: DAC vs OUT

    TI Thinks Resolved
    Part Number: AFE20408 Tool/software: In my design, AFE20408 has to drive gates for two GaN Doherty, one LDMOS Doherty devices i.e., 6 gate voltages. I am planning to give VSSA negative voltage and VCCB positive voltage. I want to use {OUTA0, OUTA2}, …
