Part Number: OPA855 Other Parts Discussed in Thread: ADS7046 , OPA856
Hello Team, We want to design a trans-impedance amplifier (TIA) using the opamp OPA855. The ADC we are using is ADS7046. The photodiode we are using is J-Series SiPM Sensors . What…
Part Number: OPA858 Other Parts Discussed in Thread: OPA657 , OPA856 I'm using the OPA858 in Transimpedance mode, connected to a Photodiode (APD).
I measured an Overshoot (277µV) at the output of this OP Amp,
at the falling of the input signal, when…
Part Number: OPA858 Other Parts Discussed in Thread: OPA855 , OPA856 , OPA615 , OPA860 Hi,
I need support about a new design.
We have a photodiode integrated in a laser diode driven by a pulse train (40mA peak, 5Hz-50kHz PRF, Duration 15ns).
We…
Part Number: OPA1611 Other Parts Discussed in Thread: OPA856 Hi Team,
A customer is looking for an alternative for OPA1611 with an open-loop gain greater than 20dB or as high as it comes at 20MHz. with low noise of 1nV/RT-HZ or up to 2nV/RT-HZ.
…
Part Number: VCA821 Other Parts Discussed in Thread: OPA820 , VCA820 , TINA-TI , OPA856
Hello Team, I am working with Automatic Gain controller on a high BW of 30MHz communication line.
For this application I have choose VCA821 VGA and OPA820 comparator…
Other Parts Discussed in Thread: OPA847 , OPA856 Hello
I would like to design a phase shifter using active allpass filter. The filter is a part of a receive chain so it must have good noise and sfdr performance. The BW is 0.5 to 2.5MHz. Can you please…
Part Number: OPA847 Other Parts Discussed in Thread: OPA856 Hello, We have a PCB circuit with the OPA847 amplifier in transimpedance configuration. We wish to work in a low gain regime with a resistance in the feedback loop of 220 Ohm. The circuit has…
Part Number: OPA838 Other Parts Discussed in Thread: OPA837 , OPA856 , OPA383 Dear all,
I have used OPA838 to design an transimpedance amplifier. This design will be used as to convert the output current of an ultrasonic transducer to voltage, the…
Part Number: OPA855DSGEVM Other Parts Discussed in Thread: OPA855 , OPA859 , OPA856 , OPA861 , TLV3603E Hello E2E Experts,
Good day.
I am interested in powering a laser diode. It is a simple design, I have a clock generator that outputs +7dBm of power…
For the higher frequency noise, i directly measure the node without wires, then oscillation can be removed
LMH34400 TIA with TLV3601 comparator.pptx
However, for the very large input current at the TIA circuit, there are relatively low frequency…
