Level shift a digital 1.8V signal to split supply rail, using BJT
I have designed a DC/DC converter (based on Zeta technology) that will generate a split supply with a single buck controller and coupled inductor.
The controller's GND pin is the negative output. ...

NE567 supply voltage
The below image lists supply voltages for NE series ICs:
Figure 1: supply voltage
Why is the IC supply voltage given as absolute positive voltage (some in thelist specify +/- values) rather than a ...

Split supply from 24V power supply using uA741 opamp
I want to connect a 0-3V analog sensor output to the 0-10V analog input of a PLC.
In order to avoid losing resolution, I have amplified the sensor signal using a non-inverting amplifier circuit (based ...

Op-amp: Why does single-supply have better PSRR?
The OPA2810 datasheet mentions:
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.
...

Parallel split rail supply with only positive regulators
I'm designing a +/-12V split rail supply for a eurorack (modular) sythesizer. I was adviced to put a pre-regulator block at a higher voltage a connecting to it several point-of-load regulators. ...

Why doesn't current flow to ground in some circuits? [duplicate]
Given the circuit drawn below, why doesn't current just go from the positive terminal of the battery straight to ground as in A. but, rather it goes round and round the circuit from the positive ...

Using 12V output as ground in 24V power supply to form +/-12V rails
I have a power supply which outputs both +12V and +24V, Here's a photo:
Can I use the +12V as ground in my circuit to have a -12V(from 0V)/+12V(from 24V) output?
The load on the -12V output will be ~...

Split power supply for battery simulator circuit is getting hot while connected to a battery charger
In order to test a Li-Ion battery charger on our board (the BQ24074) I built a battery simulator circuit which was initially designed by TI. The circuit "pretends" to be a battery and can ...

How does this voltage divider work?
I'm trying to understand how this voltage divider works with an NPN transistor in it.
If there were no transistor, V_OUT = 10.2 * 5.1k / (5.1k + 1.8k) = 7.54V
Reference to ground 7.54 - 5.1 = 2.44 V

Sanity check with 9v to regulated ±3.3v and virtual ground design
This is essentially my circuit that SHOULD get 9 v from the barrel jack connector and if that cuts off, draw the current from the battery. Basically the beginning is a simple battery backup system I ...

Single rail power to balanced
EDIT:
I built up the circuit shown below. I had the power transistors lying around, as they're a type used for class B audio amps, and they're dirt cheap on the "jungle river" website--about ...

Will asymmetric loading of my split rail supply cause problems?
I plan to use a MTU1D0509MC Series isolated DC-DC converter to power an in-amp and supply bias current for a resistive sensor. I couldn't find anything in the datasheet about asymmetric loading:
