Part Number: THS4567 Dear, Support Team. Our customer uses a transimpedance to drive the photodirector current to a differential voltage output. However, the customer seems to have an oscillating output. Please tell me how to measure the gain/phase characteristics…
Part Number: THS4567
starting to work with this a bit for an article, Here, for some reason you went balanced supplies when this type of circuit works well on single supply - also, you show the input Cm loop enable at 5V using +/-2.5V supplies, also…
Part Number: THS4567
Figure 8-1 shows the current noise in series with the inverting input - since that is a current source, it is high impedance and would open the loop.
Normally, this is modelled as a current noise to ground at the V- node, not in…
Part Number: THS4567
I was working on some example sims in just a diff voltage amplifier and kind of needed how much Icm current is available - the TINA model seems to support 1mA demand before it falls apart. Surprised this spec is not there (or at…
Part Number: THS4567 Would you please give me a hand?
Just have a look at the schematic attached as below, which is based upon THS4567.
Of couse, Vbias should be -5V or -10V, which is depend on the bias voltage of the PD.
Hello Renan,
Thank you for checking with your customer. I apologize for the lateness of my response; I have been travelling and handling an influx of assignments upon my return. As I see it, since the issue is not affecting the end requirements for the…
Part Number: THS4567 Other Parts Discussed in Thread: LMH32401 Would like to use THS4567 as differential output TIA with one (1) input photodiode. Data sheet section 8.3 Differential TIA with 0-V Biased Photodiode, presents a circuit with 0V bias (Fig…
Part Number: THS4567 Plan to use the THS4567 in a charge amplifier mode.
How is the noise modeled in the THS4567 Tina model?
I wonder if the input differential current noise and input single ended current noise are correctly modeled vs VICM and ICM enable…
