Part Number: OPA4141 Tool/software: We use OPA4141 in one of our products. We're seeing a fairly high failure rate of close to 1% of units per year coming back with catastrophic failure of the op amp, with visible burning of the package. Are there any…
Part Number: OPA4141 Other Parts Discussed in Thread: TINA-TI , OPA4992 Dear Sir:
I am using opa 4141 opamp in a PLL to lock a vco system to 350000Hz reference oscillator signal. The error should not be > 0.0003 Hz roughly..
When the opamp that derives…
It is not a good way to place capacitor at input because it introduce small phase shift at 50/60Hz thus decreasing common mode rejection. At least, my tests shows that this capacitance need to be too high to keep chopper-induced noise low... May be I…
Part Number: OPA4141 Hi, all
Can anyone tell me the difference between OPA4141AIPWR and OPA4141AIPW? is that possible OPA4141AIPW can perfectly replace OPA4141AIPWR?
Thanks, best regards
Yue
Part Number: TL084H Other Parts Discussed in Thread: OPA820 , OPA810 , MUX508 , , OPA1644 , OPA4141 , OPA2145 Hi,
I'm asking myself if there are J-FETs in the Input stage (for true MUX Friendly operation) or MOS transistors with some kind of gate protection…
Hi Kai,
Could you provide a little more detail? Does the amp need to have low or high supply voltage range? We will be able to get close but it is unlikely we can get you an exact match, so if you can let us know which specs are most important that…
Hello Trenton,
The OPA404 is a legacy product that is still supported by TI. The Electrical Specifications indicate operation down to -25 C for the KU packaged device, but likely it would continue to operate at -40 C; however, no assurances about performance…
Hi,
I recently learned about adding a terminating resistor to match the impedance of a line and prevent reflections which cause distortions and ghosting. Naturally, this feature is critical for high frequency applications.
1. Is there a frequency…
The OPA145 also looks like a good choice, this file has not been recently updated so the OPA196 is not in yet, and the pricing is out of date.
