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…
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,…
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…
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;…

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.

Part Number: LM7321 Other Parts Discussed in Thread: OPA172 , OPA2210 , OPA1652 , OPA1678 Hi,
I'd like to use this amplifier, but I find it strange that a SOT23-5 has a height tolerance up to 1.45mm while other SOT23 are ofter up to 1.1mm.
Is the 1.45mm…
Hi V 666,
The OPA197 precision op amps will likely deliver at least 15 V peak with a 600 Ohm load and +/-18 V supplies, but we have not characterized the device for this kind of load service. Certainly, the THD+N will degrade because the open-loop gain…
Part Number: OPA1642 Other Parts Discussed in Thread: OPA1652 , OPA1662 , OPA2141 , NE5532 , OPA1678 , OPA1679 , OPA1688 Hello,
I was looking for information about offset voltage temperature dependence - opa1642 spice model does not include this. Using the cross…
Hi Viktorija,
TI has newer, very high performance JFET input audio op amps such as the OPA1642, OPA1652 and OPA1656 that should perform well in many OPA2604 designs. The main differences with the newer options are their maximum supply voltage is +/-20 V …
