Dear freaks,

 

I am searching for a general purpose op amp with a 32V (max) power supply and nulling pins.

 

Can you help ?

Single rail supply?

 

If so, options include the mc34071 from onsemi and op90 from analog. The lt1006 from linear might also work.

What's it for?

 

Knowing the application might open-up some application-specific suggestions ...

Top Tips:

  1. How to properly post source code - see: https://www.avrfreaks.net/comment... - also how to properly include images/pictures
  2. "Garbage" characters on a serial terminal are (almost?) invariably due to wrong baud rate - see: https://learn.sparkfun.com/tutorials/serial-communication
  3. Wrong baud rate is usually due to not running at the speed you thought; check by blinking a LED to see if you get the speed you expected

Any old +-15V opamp has +-18V rails max,so it can run no prob from maybe 35V single supply. Need to bias the + input correctly. Harris made +-35V opamps that showed up in a lot of MCI studio mixing boards. Lots of headroom compared to +-15V swing. Still avail, but I forgot who bought them... How's the automotive project progressing? Kartman has convinced me that Freescale LIN bus alternator chips are alive and out there.

Op-amps don't have ground pins. So when you say 32 V max power supply, that means that you can use split rails of +/- 16 V or you can set the negative rail to 0 V and the positive rail to 32 V, or any weird combination you like, and it will work.

 

Since many common op-amps are on a 36 V process -- meaning it's common to run them at +/- 15 V but they'll work to +/- 18 V -- you have a big list.

 

In fact, the bog-standard 29-cent NE5534A single has a power supply range of +/- 20 V and it has compensation pins.
