  RE: LPV821: Current Sensing in No-Neutral Light Switches

  Hi Chris, No-Neutral wire switch is just a type of switch. I think that this is marketing jargon ( that is trying to confuse people, I think). The electrical circuit has to be completed in some way in order to work. The image below is the wiring differences...

  LM2664: Is there a dual output device providing ±5V?

  • Resolved

  Part Number: LM2664 Hello. I wish to power the TLV2711 low power Op Amp, supplying ±5V. When testing with my prototype, I used the USB 5V and LM2664M6X to create -5V. Now, I have to use a LiPo 3.7V with 200mAh battery instead. Considering the power consumption and the IC size, is there a dual output...

  RE: TLV9061: Damage issue

  Hi Vincent, To answer your question, I took a closer look at your original problem statement. Frankly, I do not think my initial analysis was correct. Because RS1 is so small, the voltage that will form across the resistor is likely to be small even...

  RE: LPV821: Dual supply operation

  Hello Antonio, Yes, the ability of the LPV821 output stage to swing close to the supply rails is a function of the ON resistance of the output FETs. Typical Characteristics graphs 29 through 32 in the datasheet show a resistive characteristic when sinking...
