Hi,
I have changed the the operating mode to BD and the heating issue seems to have largely gone and the PA is taking a more sensible amount of current. However, my colleague Charles originally raised a point about the hissing noise coming from the amplifier…
Other Parts Discussed in Thread: TAS5717 , TAS5713 Hi,
I am using Ti's TAS5717 audio amplifier in our board.We are using a PIC controller for programming the audio amplifier through I2C. For initial validation,we have used the eval kit for programming it…
Other Parts Discussed in Thread: TAS5717 , TAS5713 Hi,
In my design I am using TAS5717 and I notice that after I initialise the PA, it starts to dissipate around 2.5 W before I start feeding any signal to it. Looking at the datasheet it is not obvious that…
Other Parts Discussed in Thread: TAS5717EVM Dear Team:
Our customer followed our TAS5717EVM circuit and got pop noise in headphone as power on.
Do yo have any suggestion to reduce the pop noise? (Register mute, headpphone shutdown,..etc)
Other Parts Discussed in Thread: TAS5717 Hi,
I want to configure my TAS5717 in BD PWM mode.What are all registers should I update?. Please help me with the value of 0x05,0x20,and 0x25.
Other Parts Discussed in Thread: TAS5717 , TAS5717EVM Hi,
We are using TAS5717 in our board.Which PWM mode we have to set for proper working?.Initially we tried with AD mode.We were facing a noise as well inductor heating issues.Then we changed the PWM…

Using an Audio Precision analyzer with 22-22K filter, I measure the EVM headphone output noise at about -75 dBu and peak audio output of roughly +8dBu. The datasheet spec for SNR of headphone amp is 101/105 dB. I am hearing white noise that seems to…
Other Parts Discussed in Thread: TAS5717 , TAS5717EVM Hi,
Now my work is to write sw to drive the speaker, we use the TAS5717 driven by iMX6(freescale ARM CPU) to drive the speaker.
I'm new to the digital audio stuff, and I've already read the datasheet…
