I have been experiencing a problem with the output of a OPA344NA OpAmp, with a particular setup when operated at -40DegC. The device is being used as a simple non-inverting amplifier with a gain of 10.53, when operating at -40DegC and the +ve terminal…
Other Parts Discussed in Thread: TMS320F28335 , OPA344 Dear All,
I am sampling a DC bipolar voltage ( -1.5 to 1.5 volt ) and passes through a OPA344 circuit to level up to 1.5 volt using a reference voltage ic. ( ADC of TMS320F28335. )
Please help me how…
Hi Carlo,
add a 10...100n cap between pin 7 and pin 4 of XTR117. Replace all components by fresh ones.
If the circuit still doesn't work properly then, I would also remove the opto for a test and replace the opto transistor by a resistor in order to…
Hi D B17,
Are you using the surface mount SOIC package or the through hole PDIP package? If you're using the PDIP package, here is a sort of all the parts with rail to rail input and output in a PDIP:

i want to record a sound with ADC of MSP432-launch pad & Booster pack MK II with 96K SPS. in booster pack MK II TI use a 40 dB amplifier(opa344) to…
Icy,
Sorry I missed the MEMS spec of your microphone.
You can select from several options of general purpose opamps.
Your OPA344 circuit looks good, you can simulate it in WEBENCH, TINA-TI and there is also a P-SPICE model available of this device.

Hello,
There is not a direct replacement for the OPA317 in a PDIP package. Some other devices that would work in this application and are available in the PDIP package include the OPA340, OPA344, and LMC6081.

Other Parts Discussed in Thread: OPA344 Hello folks! Recently, I'm trying to interface couple of mic to my microcontroller for finding out frequency of my speech. I built a microphone module and used OPA344 for amplification.
But, Currently when i…
