Hi, Inho,
It depends of the digital activity on your design. Usually, we recommend to separate the digital activity from the analog activity since there could be some high-frequency noise content on the digital portion. There are some devices whose…
Part Number: NE5532 I have an application using an NE5532 as an audio line driver (mid-rail biased, single-ended 12V supply) and have a question regarding the output current specs. Under electrical characteristics on the datasheet, the output short circuit…
Part Number: LM4871 Other Parts Discussed in Thread: NE5532 ,
I want to know
1. The difference between audio op amps such as ne5532 and speaker amps such as lm4871 in application?
2. Can they all drive the speakers directly?
3. The audio DAC…
Part Number: NE5532 Hi Sir，
Since iaccord antecedent is turned on/off,Headphones can hear a momentary "voltage" sound. How to solve the issue? Pls give some recommendation.
Thanks a lot.

Part Number: NE5532 Dear Specialists,
My customer'd like to know the possibility of phase reversal.
According to the attached application note, PNP or JFET input stage may cause.
I don't know NE5532 is PNP input stage or not.
Could you please…
Part Number: NE5532 The power supply specification in the datasheet is VCC+ 22V maximum and VCC- -22V maximum. We are operating a device with VCC- = 0V and VCC+ = 24V. One op amp is a voltage follower to derive a 12V reference from a potential divider…
Hi Jan,
what you are talking about is the absolute maximum ratings. Summarized do they mean that the input voltages must not exceed the supply voltages. Otherwise damage will occur.
But there's another limit which decides whether the chip will work…
Hi, Francisco,
The LM837 is a good option. It is similar to the NE5532. They share similar characteristics (some minor changes like the maximum ranges). But if you are looking for some specific parameters for an operational amplifier, you may list them…
Part Number: NE5532 Following the directions in the datasheet for the Linear LTC1968, I implemented a Sallen-Key filter with buffer as per the attached schematic.
When I model the circuit in LTSpice, it works fine and is stable. On the PCB, however…
Hi, EuMesmo,
I will close this E2E thread for now. But please feel free to add further information or observations about this issue. We will be glad to help you in case additional support is required.
Thank you.
Best regards, Luis Fernando Rodríguez…
