Part Number: OPA838
Here's my schematic why I can't output a properly amplified signal when the input signal amplitude is 1.5V.
When I input a signal amplitude of 1.2V it is ok. And according to the info in the manual a 1.5V signal is not outside…
Part Number: LMX2595 Other Parts Discussed in Thread: LMX2581 , LMX2541 , LMX2485E , LMX2485 , LMX2485Q-Q1 , OPA211
Dear TI Technical Support Team,
I am designing a wideband RF signal source covering the full range of the LMX2595. My primary design challenge…
Hi,
They are similar specs, which is why the numbers are so close, but we measure them differently.
SNR is measured by grounding the ADC inputs to 0. The resulting digital output from the ADC will be the effective noise floor of the ADC. SNR by definition…
While debugging a mid-power push-pull isolated supply (~100W range), I’ve once again hit the classic wall:
Runs fine under light load MOSFET temps shoot up under full load EMI spikes appear around 180-250MHz during pre-compliance checks
The frustrating…
Part Number: ISOW7844
Hello Support team,
The isolation circuit I designed is used to collect whether the keys are grounded. I have a 3.3V input and a 3.3V output, but when I measured the voltage at the output end, it was as high as 7V. I don't understand…
Part Number: OPA858DSGEVM Other Parts Discussed in Thread: OPA858
Dear Engineer, I wo uld like to consult you regarding an issue. I previously purchased an OPA858DSGEVM evaluation module. At first, when I applied a signal to the inverting input, the circuit…
您好
Functionally the schematic looks correct. I would recommend using an RCD clamp vs a TVS clamp. It helps dampen the ringing at the switch node which will improve EMI and power stage performance.
The output voltage is sense and controlled by VS pin…
Part Number: TMS320F28379D Other Parts Discussed in Thread: SYSCONFIG
I am working with the CLB module on TMS320F28379D. I am trying to implement a simple timer (counter + FSM as T flip-flop) to toggle a GPIO, using only driverlib functions (clb.h, xbar…
Part Number: PMP41009 Other Parts Discussed in Thread: UCC28740 , , PMP41031
Hello, I am debugging a self-designed flyback switching power supply with an input of 90-900VAC and an output of 24VDC. I use the UCC28740 chip and adopt the relevant power supply…
