| Sep 6, 2021 at 19:22 | comment | added | Spehro 'speff' Pefhany | @ThreePhaseEel the cheap ones are, so they’re electrically isolated from each other. There are ones on a single die such as the venerable (and discontinued) MAT02 but they are aimed at specialized applications and are pricey. | |
| Sep 6, 2021 at 19:19 | comment | added | ThreePhaseEel | @MicroservicesOnDDD -- I was wondering if the commonly available dual packages could solve the OP's matched-transistor issues cheaply | |
| Sep 6, 2021 at 18:18 | comment | added | MicroservicesOnDDD | @ThreePhaseEel -- Were you looking for a single-die, two-transistor component? | |
| Sep 6, 2021 at 15:24 | comment | added | John Doty | @ThreePhaseEel Some are, some aren't. If they their matching specs meet your requirements, you don't care. But what are the requirements? Working your way down from top level to requirements on the components is part of an exercise like this, addressable in various ways. Build a prototype and see what consequences a deliberate mismatch has. Or analyze on paper. Or simulate. Master all of these for various kinds of circuits, you're a designer. | |
