Part Number: OPA4172 Dear members,
I've used OPA4172 for making a Sallen-Key second order low passs filter. I need to make 4 filters because the input scaling is different among them:
0.075A for Vmax=4000 Vmin=-4000
0.2A for Imax=100 Imin=-100 …
Hi Michael & Tim,
Thank you for the information, I do mentioned the problem of 10k and 47pF to the customer but since the schematic is already tested and is fined then I'll just leave it....
I do mention the 2 and the 4 channel feature to the customer…
Part Number: OPA4172 Hi Team,
Customer is consulting below amplifier's output voltage is locked to -3.8V until resetting power supply. The OPA4172 is powered by ±5V, and the input voltage of pin 2/3 is basically 0V, but pin 1 outputs is locked to be…
Part Number: OPA4172-Q1 Other Parts Discussed in Thread: OPA4172 Hi expert,
In OPA4172's datasheet, I get below information:
May I know how to do worst case analysis based on above information? Should I use full temperature range data?
BTW, what…
Part Number: OPA4172-Q1 Hi team,
Please check the circuit diagram to make sure that the circuit used is correct.
I would like to send the schematic directly later.
Best regards,

Hi Andreas,
I would use the following scheme:
This scheme allows a somewhat longer microphone cabling. Also, the supply voltage of the electret microphone is filtered. This can considerably stabilize the amplifier, as Paul already mentioned.
