Hi dear, I'm trying to set up an audio amplifier with quad half bridge STA515W.I've attached the schematic; is there anything I'm making wrong?Every time I solder in my custom PCB it blows up immediately. Please note that the circuit was designed for...
Posted on November 01, 2014 at 21:15Hello, I'm using a STA311b DSP in my actual Project and I'm wondering how the powersupply correction works? I couldn't find any details about this feature. How do I have to connect the ADC in this case? Do you hav...
Hi,We are planning to use STPM33TR in one of our switch gear product, this ADC has in built temperature compensation, and we wanted to have temperature compensation for line voltage channel should be done from external temperature sensor (far away in...
I want choose a part which has audio codec and audio amplifier in a single IC. It should support USB interface. The amplifier(chip) output is given to a speaker. It should support 3-5V supply range.Note: Speaker consume power in the range 2-4W Sp...
Hello!This is a manufacturer of PLC MODEM in Korea. My name is David Ko.Part number - TPL5010 (TI: Texas Instruments, http://www.ti.com/product/TPL5010) is what we are using IC.In 2018, our expected require number of ICs are 600,000. I would like to ...
I am using the STA350BW. While I tried to change the output gains by writing register 0x07, a noise showed up. I found that it is something relative to DRC and when the DRC is enabled, ZCE seems not work.How can I eliminate the zipper noise while tu...
I have connected a Quad ADC (ADAU1978) to I2C2 peripheral of STM32F407VGT. I ahve also enabled I2S2 peripheral to get audio data from the ADAU1978.I am using HAL API HAL_I2C_IsDeviceReady to check whether the slave is acknowledging or not. This API r...
I'm trying to work with P-Nucleo-IKA02A1 but I have some problems: 1) The data of CO that I take from the electronic circuit board with the software UNINUCLEO are not plausible. The value (made in ppm) is negative and, after a small physical pressu...
Im working on an old PPI car audio amplifier. I have a blown transistor but cant find any info about it. Everything i know is that it was made by motorola and S T in top corners P4262 across the middle R125 under that. If possible please provide su...
