Part Number: OPA1642 Other Parts Discussed in Thread: OPA1652 , OPA1688 Dear,
Is there a recommended application for OPA1642 working in +5V single power supply, is there any risk? It seems below application not working properly, it on some units get terrible…
Part Number: OPA1642 Other Parts Discussed in Thread: OPA1652 Hi team,
The following two sets of Output Voltage vs. Output Current characteristic curves seem to behave in opposite manners.
For OPA1642, the output current (limit) appears to increase with…
Part Number: OPA1642 Any chance the OPA1642 in inverting mode is stable at 1/3 gain? R1 is 10K feeding the negative input and R2 the feedback resistor is 3.33K. Needed over audio range. This seems like a no-no but I have to ask as I'm dealing with a board…
Part Number: OPA1642 Other Parts Discussed in Thread: OPA1652 , OPA1662 , OPA2141 , NE5532 , OPA1678 , OPA1679 , OPA1688 Hello,
I was looking for information about offset voltage temperature dependence - opa1642 spice model does not include this. Using the cross…
Hi Robert,
We do not have an updated model since both die variants will exist on the market until the old version is completely bought up. We do not have a way to tell a customer if they are getting the old or the new device and for this reason the conservative…
Part Number: OPA1642-Q1 Hello ,
I am looking for some informations regading the process FAB Technology of the opa1642-q1 :
-The Mask SET / The die Revision . -How we can get easily the FAB Site / The Diffusion Lot /the Wafer N°
Those requested datas…
When I mute the data stream (fixed h8000) I don't see any spur in the FFT and the voltage is about 2uVrms.
The partial schematic doesn't show it, but I placed 10uF ceramic X7R capacitors close to each REF pin of each DAC8822 IC.
I checked the…
Part Number: OPA1642 Other Parts Discussed in Thread: OPA2140 , OPA827 , , OPA140 OPA827, OPA2140 & OPA1642 source impedance and distortion issue. Dear Sir/Madam, While reviewing the datasheet OPA1642, by chance, I learnt the specifications in chapter…
Part Number: OPA1642 Hello,
I’d like to understand what the date code “1714+5” means. P/N OPA1642AIDR was procured twice, once with a date code reading "1714" and once with a date code reading "1714+5". I’d like to understand the difference I’m seeing…
Part Number: OPA1642 Other Parts Discussed in Thread: OPA1652 , OPA1662 Hi.
I have problems with the bias voltage of a buffer circuit.
I can´t manage to make the bias Vin/2. My supply is 5V. And I have tried to adjust R2 with a higher value,
but…
