    Nate
    Q: TPA3110D2 in BTL with 4Ohms and 22,5Vcc I would like to to use the TPA3110D2 in BTL. I have 22.5Vcc and 4Ohms load. the d/s specifies at Vcc >15V a min load from 4.8Ohms. What could could happen, if I use the device under this conditions? Is only the power losses which may cause problems...

    Don Dapkus
    It is possible in some situations to achieve higher output power than listed in the data sheet for an audio power amplifier (APA), but one certain cost will be increased distortion. There are also potential issues with thermal management, RMS output current levels and long term reliability. Generally...

    Question about TPA3110D2 GVDD Capacitor 1) Is it possible to change GVDD capacitor value larger, for example from 1uF to 220uF? The customer would like to change the capacitor value due to sound tune. 2) When the system is powered on AVCC/PVCC rises to 12V final value over about 2.5 seconds. Is...

    I have a customer asking the following question - "I need help on the TPA3110D2 Class-D Audio Amp demo board you got me. Can I tie the output single ended? " If this is not possible is theer a single ended part similar to the TPA3110D2? Cheers Calum

    Q: TPA3110D2 frequency response Hi team, My customer designs home theatre solutions. They are developing a 5.1 system based on TPA3110D2. On their board they see that gain rolls of at higher frequency -- around 2dB less beyond 10KHz (for resistive load as well as for 8R speakers). This...

  • Forum Post: TPA3110D2 changing gain on the fly

    Mj
    Is it possible to change the gain of TPA3110D2 on the fly ? Or maybe by changing the gain and then shutting it down and turning it back on using the !SD pin ? If yes, would it be better to pull up the Gain 0 and Gain 1 pins and connect it to uC ?

    I've built a Class-D Amplifier using the TPA3110D2. Though i can hear the output, when i see it on the DSO its all gibberish. The ferrite bead i am using is HI1812V101R-10 from Steward The filter capacitor is of 1nF. The output contains HF noise. What might be the problem ? I tried with...

    Mj
    I am using the TPA3110D2 class D amplifier. When there is no input on the channel (floating/grounded) i am getting a tiny hiss at the output. I am using LC filter at the output instead of the ferrite bead one. With ferrite bead the idle channel noise was high, using an LC filter has definitely...

  • Forum Post: TPA3111D1, TPA3112D1 over current protection threshold

    Rowan Smales
    Hi, I am using the TPA3111D1 to drive a predominantly inductive load. The design is based upon the EVM board, with an LC filter, and with -SD and -FAULT linked for automatic recovery. On the datasheet there is no figure for the current threshold at which the over current protection kicks in on this...

  • Forum Post: TPA3110D2 load impedance for BTL config

    Lakshmi Bhavani
    When the datasheet of TPA3110D2 mentions load impedance as 4 ohm or 8 ohm in graphs and electrical characteristics, Is it the physical load (speaker impedance) or the impedance seen by the amplifier at each +ve or -ve output terminal (i.e half of the actual physical load for BTL)? In other words, does...

    Mahendrakumar Reddy Ippagunta
    We have a TPA3110D2 amplifier board which is shutting down during the silence between the tracks or when there are any in the music stream due to network congestion. This shut down problem also occurs when we hot plug the input jack. Sometimes without any reason within 4-5 seconds after power on. These...

    Hello, I'm using TPA3110D2 EVM now, and I'm facing some problems: The EVM worked well before I used a multimeter to measure the voltage of each pin without any connnection of input and load. While after the measurement, the EVM board seems to go wrong, the DC output voltage without input and...

    Hi, I am using TI's TPA3110D2 now, I have one question, can this part be used as single end output? I find some answers in this forum, but why BD mode can't be used as SE output, since both output have contained the signal.

    toshi-e2e
    I would like to extend the SP wire with TPA3110D2 from 20m to 100m. Is there any information to consider the possible SP wire length? Also, please advise the LC filter design considerations for using long SP wire. Target Output power is about 3W @1% strain rate.

  • Forum Post: TPA3110D2 Floating Gain Pins

    George Ioakimedes
    I forgot to add pull downs on GAIN0 and GAIN1 and currently only have the option to pull them high which is too much gain for the current application. Any chance floating them will reduce the gain or must they be pulled either high or low?

    I've got some noise when idle on my design and since this is my first TPA3110D2 Class D amp board I wanted to get some quick feedback on what I see when measuring across the output ferrite beads. The circuit looks like this: And measuring across FB7 (L+ ferrite bead near the speaker connector...
