Quiz: How Well Do You Know Adaptive Power Switching?
Is your I/O module overheating? The AD74416H's Adaptive Power Switching (APS) can cut heat dissipation by up to 40% — but how well do you really understand how it works?

LTC6258
Last Time Buy
The LTC6258/LTC6259/LTC6260 are single/dual/quad operational amplifiers with low noise, low power, low supply voltage, and rail-to-rail inputs and outputs...

LTC6258 is end of life, I read. We use it for a mid-rail because it's stable behaviour with high capacitive load, small outline and low voltage/low power. Could someone advice on a replacement? Thanks a lot
Hello Fedde ,
Thanks for reaching out. Could we know how large your capacitive load is on your application? That would help us pick a replacement op amp.
Also, may we know what maximum voltage/power would you accept? and is the shutdown pin necessary on your application?
Best Regards,
Kenneth

Thank you for your swift response, Kenneth.
My application has a 3V power rail, mid rail is 1.25V. Less than 5mA will be used on this mid rail. Shutdown is not necessary. I use a 10uF and 100nF (both mlcc) to decouple the mid rail. (Probably 1uF should also be enough.)
Thanks for the information Fedde. Do you have schematic that you can share? Planning to compare results on LT spice simulation once I found a good replacement.
Best Regards,
Kenneth
Here's part of the schematic, most of the circuit works with an AM modulated 8kHz sine wave.
