  • LM48100Q-Q1: Continuous noise on speaker output.

    TI Thinks Resolved
    Part Number: LM48100Q-Q1 Tool/software: Hi, So i was working on the PCM-PWM converter on the controller which feeds the data to the LM48100Q-Q1 Amplifier. Now i am just initializing the PCM module and powering on the Amplifier with maximum Volume setting…

  • LM48100Q-Q1: AMP with fault detection

    TI Thinks Resolved
    Part Number: LM48100Q-Q1 Tool/software: Hi Team, We would like to find the solution that can detect the fault on speaker. At the same time, the Po should be > 0.5W when Vin is 3.3V. Can we use LM48100Q-Q1? Or do you have better solution? Regards…

  • LM48100Q-Q1: Noise in speaker output.

    TI Thinks Resolved
    Part Number: LM48100Q-Q1 Tool/software: Hi team, We are currently working on the LM48100Q-Q1 Audio Amplifier and we are observing some noise in the speaker output. This is the process we are following to feed the data to audio Amplifier. 1) We are using…

  • LM48100Q-Q1: Using Vdd to set a short circuit current limiting threshold

    Part Number: LM48100Q-Q1 Hey, I am looking at LM48100Q-Q1 datasheet. It doesn't specify how the Vdd and PVdd rails connected internally. I want to supply 3.3V to Vdd and use the current limiting feature for this part. And, I want to supply 5V to PVdd…

  • LM48100Q-Q1: Question about fault detection (short load or open load) while playing audio

    Resolved
    Part Number: LM48100Q-Q1 Hey, The LM48100Q-Q1 has a fault detection control register where one can select different fault conditions (such as open load, short load, and etc). I was hoping if someone could answer the following question: Does LM48100Q…

  • LM48100Q-Q1: Issue with audio outputs not inverting

    Part Number: LM48100Q-Q1 Hello, I have an issue where the OUT A and OUT B of the LM48100Q-Q1 are the same signal, they are not differential. For example even if a sinusoidal waveform is present at the outputs they are identical and so there is no output…

  • LM48100Q-Q1: I2C pins SDA & SCL bus max capacitance value required.

    TI Thinks Resolved
    Part Number: LM48100Q-Q1 Dear All ,LM48100QMHE/NOPB is used in one of the design and need to estimate the worst-case bus capacitance as multiple I2C devices are connected on the BUS. Unfortunately the I2C pin capacitance data is not given on the datasheet…

  • LM48100Q-Q1: application note with Flash

    Part Number: LM48100Q-Q1 We are looking for some technical document on the SPI flash chip (W25Q128JV SPI Flash) and audio amplifier from TI (LM48100Q-Q1 Mono amplifier). We are trying to understand if these chips have any controlled impedance, length matching…

  • LM48100Q-Q1: SDA Data Hold Time parameter in datasheet

    Resolved
    Part Number: LM48100Q-Q1 The SDA Data Hold Time parameter t6 is listed in Table 6.9 but does not show up in the waveform view of Figure 12. What waveform relationship is t6 referring to? Thank you

  • LM48100Q-Q1: LM48100q的开路检测功能无法实现的问题。

    TI Thinks Resolved
    Part Number: LM48100Q-Q1 各位工程师好， 我们在使用LM48100q这个音频放大器的时候，客户需要有喇叭输出端的短路检测、开路检测功能。 软件同事在调试的时候：DG_EN寄存器设置为1（打开）的时候，喇叭的输出一端对地短路的时候，pin1（fault）引脚是可以拉低为0的。 而在 喇叭的输出一端开路的时候，pin1（fault）引脚电平是没有变化的。 我们在看了规格书后，发现规格书里面写的是可以检测短路和开路的，谢谢。
