Hello!
Is the maximum recommended rail voltage for the TL972 12V total, or ±12V?
The datasheet specifies "12V", but I want to be absolutely sure whether the "±" is implied or not.
Thanks in advance.
Kind Regards,
David McRell

Hey David,
The TL972 is 12V total, ±6V.
I can tell because the abs max table has 15V listed max, therefore it couldn't be ±12V because that would be 24V.
All the best,

Hello Carolina,
In my mind, the same question applies to the abs max spec. Is the "15V" abs max a total or ±15V?
However, I believe I found the key detail.
On page 9, section 8.1, the datasheet says:
"The TL97x family of operational amplifiers operates at voltages as low as ±1.35 V"
(emphasis mine)
The max and recommended spec of "2.7V" is exactly 2x 1.35V, therefore I conclude the max and recommended spec is absolute and not ±.
