The question for the Class-D audio amplifier IC "TDA7498"
Is the internal circuit of the terminal damaged if a surge voltage of 3.6V or higher is applied to the INP and INN terminals of the Class-D audio amplifier IC "TDA7498"?Is there an element in the chip to protect against the effects of surge voltage?
TS3011 schematic for datasheet figure 19
Figure 19 in the TS3011 datasheet is a recommended layout for this high-speed comparator. But there is no corresponding schematic diagram to indicate the purposes and values of the components. Where can I find this schematic diagram?
TS922: Which circuit is suitable for achieving short circuit strength at the output?
I use the TS922 as a non-inverting amplifier with a supply voltage of 0V / 10.5V. Since the TS922 is not short-circuit proof at the output, I am looking for a suitable circuit for it.
TDA7269A Not Behaving the Same Between the Standalone Amp and the System Brd Amp
Dear Tech Support,I built up a stand-alone TDA7269A audio amp brd using one of the circuit app's of the data sheet. It worked well - clean, balanced, and the channels are independent of each other. So, I rolled the same design onto an integrated syst...
why gain is not 1 for LM324VIPT ?
Hello we have a circuit that is little sensitive, we are trying to read an analog accelerometer, our board is ready, but i noticed while working with LMV324LIPT as follower when the input voltage is higher than 4.5V the output saturates at this valu...
CO Gas Concentration Reading with the board P-Nucleo-IKA02A1.
Hello, I'm trying to tuning CO Gas reading value with the board P-Nucleo-IKA02A1.By the P-Nucleo-IKA02A1 BSP, Get_Gas_concentration function is belows..float Get_Gas_concentration(float gain, float sens){ return ((float)Get_ADC_value(ANALOG_GAS_VA...
TS332 input overvoltage at power off
Hi ST team, I am using the TS332 comparator to do a pulse length protection. It uses a capacitor on an input which charges and discharges in function of the pulse length. At power off, this capacitor remains charged at around 700mV while the device ...
