Hi Dylan,
Because the comparator output is the same amplitude as the triangle wave, the op amp output starts to saturate, which caused the inaccuracy in the frequency measurement.
I was able to get a correct sim with a +/-8V triangle wave: TLV1805Q1_TriangleWaveGenerator8V…
Hello Hirano-san,
Michael has made many good points here. It is important to consider that this is only a typical specification and that operating too close to the specification may be an unacceptable risk for the customer. A good indicator for a change…
Hello Danilo,
From SLAU508, the necessary slew rate and GBW can be found. Assuming a signal amplitude of 2.5V, which is conservative as you should not rail the outputs, and a signal frequency of 25kHz, you would need an op amp with a slew rate of 0…
Part Number: LM358A Other Parts Discussed in Thread: LM358 , TLV9002 , TLV6002 , LMV612 , TLV8542 , TLV9052 , LMV358 , LMV358A Hi,
Please find the schematic, We are using LM358AD and giving 3.3V to Opamp IN+ pins, but we are getting 2.0V on output…
Hi David,
We have quite a few of op amps that can be used as comparators. Most 5V devices can be used as comparators because they typically don't require the back to back diodes to clamp the differential input voltage. So, devices like the TLV9002,…
Hello MG,
So where in the circuit is the green signal? As I understand it, the yellow signal is at the op amp input and the blue is at the op amp output. Is this correct?
I would expect the green signal to be the output as Kai has also stated. The…
Hi Adrian,
The bandwidth of the LM6172 and LM6152 are significantly higher than the TLE2082 and the LM6152 does not appear to be unity gain stable so I would recommend using it in a buffer configuration. Does the customer need the bandwidth and slew…
Hi Bhautik,
I recommend taking a look at our Op Amp Cookbook . There are a lot of helpful circuits in there to help achieve what you want to do. Specifically I recommend the "Non-inverting op amp with inverting positive reference voltage circuit" on…
Part Number: TLV9054 Other Parts Discussed in Thread: INA500 , Dear team,
My customer would like to configure function of differential to single-ended using one op amp.
- Input signal : +-2.5V differential signal , Vp-p : 5V
- output signal : 0…
Part Number: TLV9051 Customer is using TLV9051 in the configuration shown below.
Any concerns with the 1 uF output capacitor? We understand it is more than recommended in the data sheet.
Thanks, Mark
