TS472

Hi!I'm want to use the component TS472. When I use an input signal -30dBu and a gain 40db it's work fine. When I use an input signalwith 0dBu and a gain 0dB it doesn't word. I don't know why. The outputsignal is less then 1Vpp and not the wave from t...

I'm looking for an ultra-low power opamp (sub-microamp quiescent current) and gain bandwidth in the 1MHz range. I looked at the TSU112, but the bandwidth was too narrow.

Enable ADC1 in DMA mode on STEVAL-STLKT01

Hi, I am trying to make the ADC1 on the SensorTile Evaluation board work in DMA mode. I have already gotten great help from @berendi on the interrupt mode for the ADC. I am still following this tutorial more or less: https://visualgdb.com/tutorials/...

I am looking for an ultra fast OP-AMP which can withstand negative voltage spikes

The specs the OP-AMP should have are:Supply voltage 3- 15 V single supplypropagation delay < 50 nsable to withstand negative voltage spikes of -3.5 V (duration is less than 50 ns, occurency 150 kHz)Thank you for your help

I need to purchase the prototype/engineering version of the RHF310A op-amp. No stock seems to be available at your distributors. We will eventually need space qualified parts, but now, any non-flight qualified version will do.

How long will the TS932IDT IC approximately be available? How long for sure? Or can you recommend a similar newer amplifier with a longer life cycle?

Low Layer DMA DAC does not start

Hello,i try for moths to get a wave file from SD to the DAC. I the ST LL_DAC_ADC_project description stands.############################################# LL_DAC_EnableDMAReq(DAC1, LL_DAC_CHANNEL_1); // enable DMA for Channel1 LL_DAC_Enable(DAC1, LL_D...

Where can I get Android Drivers for the STA369 Amplifier Chip...?

TSV630 Logic High Level Voltage

Hi,I'm doing a design with TSV630. VCC+ is 3.5 V and VCC- is GND and GAIN=1. What is the minimum Voltage for the SHDN pin to switch the device on? I couldn't find a formular in datasheet. In Datasheed there are only mentioned the different minimum SH...
