I am building a guitar amplifier based on this design: 40W Guitar Amplifier (P27) (sound-au.com) . I plan to use a OPA1656 for the first and second stages and would…
Part Number: OPA2134 Other Parts Discussed in Thread: OPA1656 , OPA134 Hi Team,
My customer wants to replace OPA1656 with OPA2134. Which one has better electrical characteristics? will replacement of the chip affect the sound?Any things should take into…
Part Number: OPA1656 Other Parts Discussed in Thread: LM27762 Hi Sir,
Do you have differential to single-end reference circuit for OPA1656?
My customer would like uses OPA1656 in headset application, thanks. (CXD3782 is differential outpt)
Thanks, Ian…
Part Number: OPA1656 Other Parts Discussed in Thread: OPA810
With the TINA model corrected, can also go on to test this 20Hz to 20kHz integrated input noise Vrms in this spec line, this also gives very close agreement to the this number indicating the…
Part Number: OPA1656 Lets start over with the right part number in the question
Reviewing this device for some audio work, the front page noise plot is ok, kind of a high noise corner but good for JFET,
Here is that from the front page, a little over…
Part Number: OPA1656 Other Parts Discussed in Thread: LM4562 , Hello,
I am designing a phono pre-amp and found application report SNAA046A–July 2007–Revised May 2013. Can I please ask two questions.
1) Can I replace the LME49710 / LM4562 referred…
Part Number: OPA1656 Other Parts Discussed in Thread: OPA1612 , OPA828 Dear all,
aiming to keep THD+N figures constant over the audio frequency range.
As per datasheet Fig 7, OPA1656 achieves this pretty well with loads of 2k (or more) @ output voltage…
Other Parts Discussed in Thread: DRV135 , OPA1656 Hi,
I'm prototyping a PCB using the TLV75733P voltage regulator, OPA1656 Burr-Brown Op-Amp, and DRV135 Balanced Line Driver, and I would like to run a simulation of the circuit in Autodesk EAGLE using a…
Part Number: OPA1656 Other Parts Discussed in Thread: OPA2134 , OPA2604
The OPA1656 is the industry’s lowest voltage noise high voltage CMOS on the market. It offers exceptional performance in almost any audio application. The low voltage noise combined…
Hi Santosh,
The design below is for the electret microphone where R1 to the supply biases the JFET. Since your microphone does not require this biasing; applying biasing may cause problems. I am not sure how your circuit is wired up. Using a design such…
