Other Parts Discussed in Thread: OPA2140 , OPA2171 , OPA1652 , OPA141 , OPA2132 , OPA2134 Hello,
I'm Ryuji Asaka.
I reviewing precision amp OPA1652, OPA2140 and OPA2171.
I want to know whether these device has "Popcorn Noise" .
Please let…
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…
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…
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…
Part Number: OPA1662 Other Parts Discussed in Thread: OPA1652 Tool/software: Hi,
I designed and built this circuit as a differential ADC input stage.
If I select the x4 gain or x8 gain (changing R3 value) the outputs are completly unbalanced.
If…

Hi Azusa,
AZUSA IWATA said: When was the EOL letter for the OPA2604AU issued?
The dual package of OPA604 may have been obsolete for several years now. The part was discontinued and obsolete for at least 5 years now, may be as early as 2015, see the…
Part Number: OPA1678 Other Parts Discussed in Thread: OPA1652 , OPA1662 Hi there!
We are looking for a replacement for the OPA1678IDGKR, which we are having a lot of trouble sourcing, in a MSOP-8 (VSSOP) package, similar dimensions, 3.00mm x 3.00mm…
Part Number: OPA1642 Other Parts Discussed in Thread: OPA1652 , OPA1688 Dear,
Is there a recommended application for OPA1642 working in +5V single power supply, is there any risk? It seems below application not working properly, it on some units get…
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 +/…
