#155239 - Chosen Op-Amp : CA5420A Responding to: ???'s previous message |
The CA5420A from Intersil seems to satisfy all requirements for this application : Rail to rail compliance; optimized for unity gain buffer applications; can operate from single supplies and specifically for 3.3V supplies.
Looks OK ? Thanks for pointing out this. Raghu |
