Part Number: LP2902

Greetings,

Is LP2902 a rail to rail Opa?

I can find the info of in to V- rail to rail in product details, but I can not find any info to be mentioned rail to rail in datasheet.

Thanks,

Regards,

    Hello Yumiko,

    Input range is 0V to VCC - 1.5V and output range is 1V to VCC - 1.9V.  Therefore neither input nor output is rail to rail.  

    Note that either VOL and VOH (not both) can be improved to rail if the output load (including feedback) terminates to GND or VCC. The output of the LP2902 will not fight a pull down or pull up resistor.
