I have an input sine wave at 300mV peak to peak. I want to filter this sine wave to eliminate noise and distortion.



I am planning to use the LMx58-N op-amp family, powered using a single supply: 3V to 32V.



Circuitry proposed will be based on the Multiple-Feedback Topology, as shown:



enter image description here



Considering the input signal to be at 100kHz +-10%, I want the filter to work adequately and without any damage to the op-amp. I also want to adhere to good electronic design principles.



Can I pass the signal directly into the above circuit, or should I bias the input signal ?



Any tips and/or suggestions would be greatly appreciated.

  • Read the datasheet! Section 6.1 Absolute Maximum Ratings gives the absolute minimum input voltage. But that's to avoid damage, not necessarily for practical operation.

    This circuit is DC-blocked by Cin. Thus DC components do not matter.

The bias is signposted already as Vcc/2 (mid-rail supply). In the quiescent state VOUT will be at Vcc too so you may need a DC-blocking capacitor on the output too.



R1 and R2 are a potential divider and form an input attenuator.



Read the datasheet carefully to understand what the maximum output voltage swing can be when operating at low voltage at the load resistance value you are proposing.

  • Many thanks for your suggestions and pointers. I am a beginner when it comes to electronics and do not fully understand your last sentence. Are you referring to the voltage gain that can be achieved when operating at the proposed voltage and load resistance?

    Yes. Operational amplifier circuits often have outputs that can not come close to the power supply rails. An output that can't drive closer than two diode drops is common (because of a double emitter follower in the output stage). This often comes as a surprise to the newbie (and sometimes even the experienced). There are op-amps that can swing the output from rail to rail -- but you have to find them.

One-line joke

A one-liner is a joke that is delivered in a single line. A good one-liner is said to be pithy - concise and meaningful. [1] Comedians and actors use this comedic method as part of their act, e.g. Jimmy Carr, Tommy Cooper, Rodney Dangerfield, Norm Macdonald, Ken Dodd, Stewart Francis, Zach Galifianakis, Mitch Hedberg, Anthony Jeselnik, Milton Jones, Shappi Khorsandi, Jay London, Mark Linn-Baker, Demetri Martin, Groucho Marx, Dan Mintz, Emo Philips, Tim Vine, Steven Wright and Henny Youngman and Arnold Schwarzenegger. [ citation needed ] Many fictional characters are also known to deliver one-liners, including James Bond, who usually includes pithy and laconic quips after disposing of a villain. [ citation needed ] Examples "A baby seal walks into a club." "A dyslexic man walks into a bra." (Anonymous) "There are three types of people, those who can count and those who can't." "Venison's dear, isn't it?" (Jimmy Carr) "An escala...
