I used the model of OP413 to simulate the noise current density and the result is correct, please tell me whether the spice model of OP413 is correct?
I have a task to optimize noise in BW 10Hz - 10kHz.
Voltage gain shall be around 20..50. OA connected directly to source of signal,
which has impedance 1kOm DC and 50Om AC. OA connected to middle point of R1/R2 divider,
where R1 connected…
Do you have amplifier (opamps) without internal bias-compensation?
We have two different types of bipolar amplifiers in our portfolio. Simple bipolar and bias-compensated bipolar amplifiers. (See app_eng.pdf on page 9 bottom left) Opamps without…
