Part Number: OPA172 Other Parts Discussed in Thread: JFE150 , OPA1656 Tool/software: We've considered the TIDU765 reference design & trying to adapt the circuit as per the microphone specification. The microphone that's readily available(CB Cobra microphone…
Part Number: OPA172 Other Parts Discussed in Thread: PSPICE-FOR-TI , TINA-TI Tool/software: Hello,
I am currently trying to build this circuit in LTSpice: AC-coupled transimpedance amplifier circuit (ti.com)
This is my current circuit along with its…
Part Number: OPA172 Other Parts Discussed in Thread: TINA-TI , Hello,
using Tina-TI, I'm running AC analysis for this fairly simple circuit. Its *.tsc file is attached below.
According to application note SBOA325, capacitor C1 provides a high-frequency…
Tapajit.
Op amp IOP1 is not fully correcting for supply drop. Perhaps N1 is starting to conduct some current. Check voltage across R9 and gate voltage for N1.

Part Number: OPA172 Even though the part is advertised a s a rail to rail output op amp, it is not. The output does not get to the positive rail.
TI, you wasted my time.
Part Number: OPA172 Other Parts Discussed in Thread: LM324 May I know the OPA172 has a internal series resistor 2.5k ohm in each IN- and IN+?
We had try to short IN- to ground (base on figure 46). We find OPA172 has higher short current than LM324. Do…
Part Number: OPA172 Hello Team,
My customer uses the preamp circuit based on TI's application note TIDU765. This application details how to uses a TI OPA172 opamp as an audio preamp for a condenser microphone capsule. They implemented the design, and…
Part Number: OPA172 Other Parts Discussed in Thread: TLV9061 Hi Sir,
The question is not exactly for OPA172 but looking for microphone preamp solution.
My customer searching a suitable low voltage microphone compression IC for ANC analog feedforward mic…
Part Number: OPA172 Thank you very much for your help.
I want to protect the circuit from the voltage applied to the output when VCC is not supplied to the OPA172. Can you tell me the appropriate circuit configuration?
In normal operation, 12v is supplied…
