Other Parts Discussed in Thread: LF347 , OPA1652 , OPA4172 Hello,
Our customer is trying to replace a LF347 operational amplifier with the OPA1652. Circuit implementation < below >.
The circuit output labeled as PIN_C is an external connection point…
Other Parts Discussed in Thread: OPA1652 , OPA1642 I need some help understanding input common mode voltage range. As a basis for the discussion lets start with a OPA1652. Vcm for this device is stated in the data sheet as:
VCM Common-mode voltage range…
Jon,
As I had mentioned previously, the best way to avoid the problem with popcorn noise would be to use our CMOS op amps, like OPA1652 or OPA2171, that do NOT exhibit this problem.
OPA2132 and OPA2140 use JFET input differential pair together with bipolar…
Other Parts Discussed in Thread: OPA1652 , OPA1662 , OPA1612 , OPA827 , OPA627 OPA1652 Input current noise density data sheet question.
The data sheet says it's 0.5pA/RtHz which seems high for a JFET or CMOS op amp.
Then, there is no graph for the input…
Hi,
what do you mean by "very high failure rate"? Do you have any numbers?
Doing a similar calculation as shown in this link

Other Parts Discussed in Thread: OPA1652 , OPA2348 , TL972 , OPA2171 , OPA4171 I have a data sheet for the OPA1652/1654 devices. No one seems to have stock (including TI -lol). Was this a future device that never happened? Can you recommend a device like this;…
Dear Chris,
The defected units can pass signal but some of them have terrible pop noise, replaced OPA1642 it may solve the problem, but the failure rate is too high 13% out of 120 units. The design was used OPA1652 that it goes OK in past production,…
Hi Ivan,
Is the schematic in this thread the correct one? https://e2e.ti.com/support/audio-group/audio/f/audio-forum/893084/pp-salb2-evm-schematics
My understanding of the ADS1271 ADC and its associated signal conditioning circuitry (p. 3) is that the…

Hi team,
Could you please suggest BA3308F TI cross?
My customer is looking for EOL replacement device.
ALC is not needed, please just recommend hero dual audio amps.
