Part Number: OPA1642 My question is what is a ballpark number for the capacitance of the ESD diodes inside the OPA1642 op-amp.
I'm using the OPA1642 as a transimpedance amplifier for a photodiode. TIA gain (the TIA is a capacitive TIA, with a voltage…
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: 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: DIP-ADAPTER-EVM , OPA2134 , RC4558 , TL072 Hello,
I have on hand 3 OPA1642s.
My Technics SU-V9 is having relay issues, and needs a recap, and possible opamp change. The currenty is AN6552. I can get an…
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…
