Re: 1.8V opamps <15c/channel?

Hello Frank,


... Why are all those 1.5V and 1.8V amps so
freaking expensive? More profit margin?

Perhaps because they don't want to go belly-up so that you can
buy from them next year as well. A healthy business sense, I'd say ;)


We can buy the LM324 for around 10c a pop for many years and they didn't go belly up from that. What makes a LV opamp so much more expensive?

Keeping prices high in anticipation that the market will bear it can backfire. For my designs I can only say that this happens a lot. Many times there was that perfect chip but I opted for a discrete solution based on cost. Nice AGC amp but I went the PIN diode route. Great S/H chip but I went the xfmr/diode pair route. And so on, you name it. That's lots of missed sales. Sometimes this isn't understood by semi mfgs executives. Once a certain design is released it takes a major earth shattering event to change it.

A classical example was the switched capacitor filter. I used them in one design but that was more based on a client's wish. Never again. Now appear to be more or less gone from a biz point of view.
