  • TPA3251: Capacitor value on AVDD and DVDD PINs

    TI Thinks Resolved
    Part Number: TPA3251 The datasheet for TPA3251 suggests in Figure 25 to use a 1uf capacitor on DVDD pin11 to GND and a 1uf capacitor on AVDD pin14 to GND. What is the maximum capacitor value that can be safely used on each pin to avoid any (power on)…

  • TPA3251: TPA3251 PBTL

    TI Thinks Resolved
    Part Number: TPA3251 Other Parts Discussed in Thread: TAS3251 Hi Sir, We know TAS3251 PBTL o/p support only 2* inductors connection. Pls advise TPA33251 also support 2* inductors connection for PBTL o/p? Thanks, Ian.

  • TPA3251: Akira-Series: CLIP_OTW pin for power supply control

    TI Thinks Resolved
    Part Number: TPA3251 Hey everyone, as stated in the Datasheet of the TPA325x-Series ICs: 10.2.1.2 Detailed Design Procedures - The CLIP signal is indicating that the output is approaching clipping. The signal can be used to either an audio volume decrease…
