I understand that the laser diode operates at the higher bias current and the only reason to lower the operating point was to determine what controls the total current noise. In the above case, it is not OPA392 but rather current level thru T1 that dominates…
Part Number: OPA392 Tool/software: Hello,
I'd like to get back to a thread that has been locked since:

Part Number: OPA392 Tool/software: I am trying to implement a differential charge amplifier, can some one please let me know what is wrong with my simulation.
Sensor is piezo with 11 nF capacitance, frequency of range is 10 Hz to 15 KHz, minimum signal…
Part Number: OPA392 Tool/software: Hello TI,
I am looking for an opamp with with following parameters:
1) Auto zeroing
2) Input bias current: 1-1000 fA
3) input offset voltage: 5nV-500 nV
4) input offset drift: 1 - 5 nV/DegC
5) noise: 1) F @ 1 Hz 1nV…
Part Number: OPA392 Other Parts Discussed in Thread: OPA378 Tool/software: Hi TI,
What is the difference between EMI hardening and EMI filtering? Some opamps (e.g. OPA378) are labeled as 'EMI hardened' while some (e.g. OPA392) are just(?) 'EMI filtered…
Part Number: OPA392 Tool/software: Hi TI,
What would be the max Vin voltage in the scenario presented below, without using additional over-voltage protection diodes? In another words, what is the max current internal diodes can withstand? I was unable…
Part Number: OPA392 Other Parts Discussed in Thread: OPA928 Hi,
We are evaluating OPA392, but drift occurs at high temperatures of 120℃. At room temperature, it operates normally and no drift occurs.
The cause is probably a leak between the sensor's input…
Hi Dan,
I don't mean to dismiss this as a basic topic, I just wanted to be sure you were aware of the noise presentations. Actually this is a tricky problem.
Eventually, the output impedance will start to fall over frequency, because the parasitic…
