It is a classic problem when designing with op amps: you need the output to go to zero, but — for most op amps — you can’t quite get down to the supply rail. If your power options are a positive ...

It seems to me that the -5V and -12V lines are pretty much obsolete and just thrown in for compatibility reasons. As a matter of fact the SFX power supply standard drops the -5V entirely but keeps the ...

Negative power rails are used with key IC building blocks such as digital-to-analog converters (DACs), analog-to-digital converters (ADCs), operational amplifiers, and GaAs FET biasing. Symmetrical ...

There comes a time in every hardware hacker’s career during which they first realize they need a negative voltage rail in their project. There also comes a time, usually ~10ms after realizing this, ...
