目�?�?用的LM358芯片，�?�电压跟�?器，出现输入电压V+为0V时输出电压有�??几�?
现在有一个项目上用了LM358�?放，�?�电压跟�?器用，用在电机上的，现在出现的问题如下：358是15V供电�?�了一百多�?��?��?，有差�?多五六个出现了下述情况，�?良的芯片输入电压V+为0V时输出电压有�??几�?，�?良的芯片正常工作时，输出电压�?�是正常的，�?�是输入电压是多少输出电压就是多少。项目比较急，麻烦尽快帮分�?下原因原�?�图如下:

How to partially discharge TDA7419 spectrum analyzer capacitors?
Dears, Good morning.Regarding TDA7419's spectrum analyzer, the datasheet says:"A reset of the sample capacitors is induced whenever SAclk remains high for the time tintres" From the tables, Tintres is 3ms.Question: Is there a way to partially dischar...
Resolved! the commercial product part # was different finished goods part #
Is commercial product part # supposed to match exactly with the finished goods part# in its basic part (USBLC6-2P6), would you explain the finished product code with “/J�? means in this case?
Resolved! would you check and explain what is different in between USBLC6-2P6 and USBLC6-2P6/J
would you check and explain what is different in between USBLC6-2P6 and USBLC6-2P6/J
TS4909 - high white noise output
Hi all!I've been strugling with this TS4909 for 2 weeks now, and cannot get it work properly...I've designed a custom application with TS4909 as audio amp.The problem is is has high white noise on the output.My power supply is clean (from LDO), no no...
STA350BW delay
Hello everyone,I'm working on nucleo-f446re and x-nucleo-cca01m1 demoboard, using last version of FP-AUD-SMARTMIC1 software.The STM32F4 sends audio data to two speakers through the STA350BW via I2S interface.The output sampling frequency is 32kHz. I2...
Power supply suggestions for powering 3.3V audio processor from supply rails of TDA7293
Hello,I am using +/-40V to power TDA7293 and have no issues with its application. I want to power an audio processor from the +40 supply rail. The audio processor needs 3.3V.Kindly suggest a scheme to achieve this.I am concerned about the power dissi...
MTBF(mean time between failure) of LMV321ILT
would you let me know MTBF or FIT value of LMV321ILT??thank you.
Is it possible to use the I2S peripheral as slave interface without an external MCLK ?
When I googled this, I only found documentation for SAI peripheral slave interface which indicates SAI slave works without MCLK in I2S mode.Nothing about I2S peripheral slave interface, though.I am working with the STM32F411CEU6, which has I2S but n...
