  • RE: TPA2025D1: TPA2025 -Operating quiescent current

    Resolved
    Hi Switch, It's been some long time since last communication, but I've got some test results from EVM: I measure ~5mA quiescent current when powering the EVM from 3.6V. This is with the inductor in place. However boost is not enabled (PVDD ~…

  • TPA2025D1: Overheating issues

    Resolved
    Part Number: TPA2025D1 Hello I have designed and built prototype amplifier circuits using the TPA2025D1 chip and the design largely mirrors the schematic found in the TPA2025D1EVM datasheet. I am using the circuits to drive 8 ohm voice coil shakers. …

  • TPA2025D1: Tuning gain

    Resolved
    Part Number: TPA2025D1 Other Parts Discussed in Thread: TPA2015D1 I understand that TPA2025 has a fixed gain of 20dB. Can we use external circuit to reduce the gain? (For example using resistors?) Objective is to maximise the dynamic range of MCU DAC…
