Part Number: OPA552 Other Parts Discussed in Thread: TINA-TI , OPA551 , OPA683
Hello,
I am using OPA552 to make a 2nd order sallen key low pass filter. The LTSpice simulation shows stable results, however after implementing the hardware the output…
Finished some other things, and came back to this to try a LG sim how I would do it.
This approach traces the signal around the loop and adds Ccm+Cdiff at the summing node where LG is measured. Here, I get a good sim but cannot map LG=0dB crossover…
Hi 5292311,
the output voltage swing of OPA552 is limited and cannot reach the supply rails. See the "voltage output" specifications on page 6 of datasheet. See also figure 8 of datasheet.

Part Number: OPA552 Other Parts Discussed in Thread: OPA551 I use 2 OPA552P. One is configured as a non-inverting amplifier.
The other one is configured as a unity gain buffer. On the breadboard, all OPA552 is connected to + - 30V power supply with…
Part Number: OPA552 I have the OPA552 opamp in a circuit with a gain of ~6.5. I dropped the resistor values and now I have a clean signal. I have two of these in a circuit and one is used as a simple 40v switch for DC current. Both are driving resistor…
Hi Doug,
Michael is right on the mark; this is a low phase margin issue. That very large ripple especially evident with the second pulse in the upper image, having almost 5 V overshoot would indicate a phase margin of about 35 %. At least that is what…

Hi guys. I'm trying to make a custom PCB (FR-4 2-layer 1.6T) with OPA552 SOIC package.

Hi, all.
After trying the SLAA869, I was curious about converting a PWM signal as a DAC output using Op Amps.
I did notice videos using low pass filters to create a DAC output.
However, I noticed the RC delay effect when…
Part Number: OPA552
Hi, guys. I'm using Arduino DUE's DAC and a high pass filter to create the above pulse.
I'm using OPA552PA supplying + - 30 V and the aforementioned pulse is the V_in (positive input).
R1 = 150k, R2 = 10k Ohm
When my input…
