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
0.21A…

Hi all,
The customer wants to replace OP275 by our OPA4172.
But the customers are worried about the effect of difference of the voltage gain in this audio application…
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 information…
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.

Hello Steve,
Great question! For specifications such as input bias current, on some parts TI specifies a T = 25C value as well as an extended or 'full [temperature] range' value. For the THS3001, the maximum value listed at T = 25C is the 'typical…
