Dip into the complex metering modes on a modern digital camera and it’s easy to forget that photographers once relied on dedicated handheld devices to meticulously measure light before firing the ...

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 ...

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 ...

High-side current-sense amplifiers (CSAs) are principally used for monitoring the current from a positive supply rail. However, applications like ISDN and telecom power supplies require CSAs that ...

Last time, I teased you about the dark side of op-amp supply current, especially when we’re talking about negative supply pins and how the Single Supply Gang are going around connecting all those pins ...

Some circuits need a negative supply voltage that only has to supply a small current. Providing a separate transformer winding for this (possibly even with a rectifier and filter capacitor) would be a ...
