Greetings; I have application where I need to make a few differential amps, so Beta match is important. What I am wondering, while not guaranteed, how closely matched do you think 2 transistors are if they are on same die such as in a transistor array? For example: https://www.mouser.com/ProductDetai...GAEpiMZZMshyDBzk1/Wi7dklbCN21lXxt0C%2bj5He94=
One would think they should be pretty close, right? You may be asking "Hey! Mike, what is the reason you don't just purchase matched transistor arrays?"
Well, I have about $8.00 reasons. Device mentioned above $.37, matched array $8.00 Also would diode arrays be a close match for Vf as well.
Mucho Gracias
