I am looking for an OPAMP working down to 3.3V, SP or SEP.
In the application=, it will be used as in a comparator mode with small output current level: 3 to 5ma max
don't need real sophisticated performance but my goal is to drive a NPN base transistor through a series resistor (Emitter to GND)
then Vol/Voh shall allow proper ON/OFF operation
Supply level can be adjusted from 3.3 to 4.5V
LM124A datasheet does not show much data about Vol and Voh performances at low supply level and low current.
Q1 Can you provide some ?
Q2 Do you have another OPAMP that could be used as a superior or good substitute?
I was also trying to understand the difference between these 2 part numbers:
LM124AWGRQMLV 5962R9950402VZA (more expensive by 40$)
From Octopart, 402VZA model seems to have better performance (slew rate)...but I can not find this information on TI web site
Q3 Can you tell me where I can find this information ?
