WebIf this is not possible, the supply voltage rails can be extended in order to extend the common-mode range. For a single-supply op amp, this means extending the negative rail slightly below ground. In Figure 2, TPS7A39 is used to create supply rails of -0.25 V and +5.25 V to avoid non-linearity. Figure 2. Widened supply rails to accommodate the ... Web23 May 2003 · Hi, I've got this 0-30V 0-2A supply that I would like to use to test my power amplifier channels because it has current sensing/limiting. I know theres a way with a few resistors and an op amp that you can split a supply creating a 'virtual ground'. Web19 Nov 2015 · With the resistor approach you always get a nice even split. A virtual ground (in my thinking) is needed when you have a single supply op-amp but you need to amplify a signal which would go below the supply rail. For example: you get a sine-wave with 1 V peak-peak, referenced to your ground, so it goes from -0.5 V to 0.5 V. owens corning weatherguard hp

Web3 Apr 2024 · An additional advantage of configuring an amplifier for single-supply operation is that the effects of PSRR are minimized because the low-supply rail is grounded. This description is unclear. I guess this is because a split supply (+/-Vs) introduces not only +Vs noise, but also -Vs noise.
