Part Number: OPA4227 Tool/software: Dear Team,
Kindly advise correct MSL level for MPN# OPA4227UA as there is same MPN but two difference MSL found. MSL 3 mentioned in TI website but on the material MPN label MSL 2.
Part Number: OPA4227 Other Parts Discussed in Thread: OPA277 Tool/software: Hi team,
This is FAE Jayden, ZTE is evaluating OPA4277UA/2K5 and they have some questions about this device:
When used as a voltage follower, if the input is left floating…
Part Number: OPA4227 Hello, Let me confirm whether you have ever heard following condition. Could you confirm below and give me your opinion or comment ? * My customer use OPA4227. They use 4ch opamp with voltage follower. However, in their case, sometimes…
Part Number: OPA4227 This is Joong-hyeok Lee, DMSMS researcher of Leoinnovision. Leoinnovision is the official EOL(End Of-Life)/obsolescence part manager of Korean Military (Army, Navy, Air force) and PLM agency of many defense industries (Hanwha, ADD…
Hello Jwan,
Each op amp internal to the OPA4227 typically draws about 3.8 mA of current, or 15.2 mA for all four. Using +/-15 V supplies, or 30 V total, the power dissipation P D would be 0.456 W. If we want to estimate the package temperature (Tc)…
Other Parts Discussed in Thread: OPA4227 , OPA4209 What are the main difference including the internal designing of the ICs between the OPA4227 and OPA4209?
We had checked the performance of both the ICs by doing simulations but found that both give…
Other Parts Discussed in Thread: OPA4227 Hello,
I am an electronic design engineer in France. I am reaching out regarding the use of your amplifier quad HA3-5104-5 (DIP14) in one of our products. We are seeking a replacement due to the imminent obsolescence…
Hi Yordan,
the OPA4228 is a decompensated version of the OPA4227 and is very much faster than the OPA4227. But the OPA4228 can only be used with a gain greater than 5. Theoretically, you could replace the first OPAmp in the circuit (U3 in my last simulation…
Hi Shekhar,
Since you are indeed using the OPA4227 there is the issue of the much higher power dissipation that I previously mentioned. Certainly, that device will get hotter than the OPA4277.
Otherwise, I don't really see anything about your circuit…
