can i make stereo speaker for computer using TDA7269A ?
my old tea2025b speaker stopped working ,can i use this ic to make new stereo speakers or there is another better ic for making speakers ?

Evaluation of circuit design for Overcurrent / Short circuit detection
Good afternoon!Please rate my first experience in analog circuitry.The following task was released: to develop low cost a DC overload protection circuit (cut-off consumption more than 1.8A).Explanations for the scheme:A low-pass filter was made on th...
Resolved! Does ST provide SPICE models for comparators?
Just wondering if ST provides a SPICE library for the TS985 comparator? I haven't used many parts from ST and could help with any advice. My goal would be to simulate the comparator within LTSpice.Thanks,Alan
Resolved! About output waveform problem of CS42L51
Hi,This is my previous question(link).I'm implementing 24bit, 44.1kHz audio out code using STM32H7B3-discovery.In previous question, i set SAI(I2S format) buffer like below.I set SAI_A block to output.And, this is my SAI_A setting.I set tx buffer t...
Additive noise on TSC2010/11 output when sensing current while PWM being applied in BLDC application.
I have a BLDC motor drive that uses the TSC2011 in each phase leg to sense phase current. When I am PWMing the phase to inject current to drive the motor, I am getting additive noise on the TSC2011. The output sense from the device increases/decrease...
Resolved! Can single TDA7293 handle 100W RMS with 4 ohms?
Hello,I am planning to build amplifier based on single TDA7293 SoC, in class G (as described in technical note). I have 2 voltages, +22/-22 and +45/-45V. The speaker has 4 ohms. Can TDA7293 handle the 100W RMS power, or it is too much for single chip...
TSV791/2 Output Impedance
Hello, I am interested in using theTSV791/2 for ADC driver and reference buffer purposes.The reference buffer needs to both source AND sink significant amounts of current (mA) and I am interested in the amplifier's transient response.I did not see an...
We're using 3 of the TSC2011 amps to measure currents from our 3-phase H-bridge FETs to a 28VDC brushless DC motor. When driving the PWM out, we're seeing 100-300mV DC offsets on the TSC2011 Vout, making them inaccurate. Is this expected?
Is this due to noise, common mode voltage, or the PWM edges? Any recommendations to improve the circuit?
