Part Number: OPA172 Other Parts Discussed in Thread: OPA322 I'm a newbie, so please bear with me.
I made this pleamp - https://www.ti.com/lit/ug/tidu765/tidu765.pd f - and it kind of works. But I made it with another mic model - https://mouser.com/datasheet…
Part Number: OPA172 Other Parts Discussed in Thread: OPA192 Hi Guys
Our customer is using our opa172 as current sense. Please see below the schematic:
But when they use it test the output current, the OPA172 Amp's output will be noisy or oscillated…
Part Number: OPA172 Greetings everyone,
I am going through the TIDU765 design (John Caldwell) and I need to know if it would not be better to add an adaptation network between the microphone output and C3, since the input impedance of the TIA is very low…
Part Number: OPA172 Hi,
I am facing trouble in setting the gain of the OPA172 amplifier.
I want to set 20 as gain.
Should i go through the formula(1+R3/R4) or by the traditional formula (-Rf/Rin)
Please advice.
Thanks,
Kumar.V

Hi Carolin,
I've got the samples and tested OPA172, TLV172 and TLV9361. For active load (40-300 oHm) all behave similar; no visible distirtion for 60kHz sinus. But for hard capacitive load (300oHm+40nF in parallel; RISO of 10 oHm) I noticed differences…
