  • TPA2006D1: Enabling the device causes a power rail drop

    Resolved
    Part Number: TPA2006D1 Hey, This device is connected to a 3.6V power rail. When enabling the device, it causes a voltage drop pulse causing the voltage to drop to about 1.88V in less than 380uS. This pulse then generates a reset on the microcontroller…

  • TPA2006D1: white noise hearable through speaker

    TI Thinks Resolved
    Part Number: TPA2006D1 Hi team, We found that there's a hearable noise (spectrum from 200Hz to 20kHz) through speaker even we didn't give any input source. Even if we remove C36 and C37 (open circuit) and use battery for 4.2V power, the noise still…
