(4) Supply voltage rejection ratio is measured for both supply magnitudes increasing or decreasing simultaneously in accordance with
common practice from VS = ± 5V to ±15V for the LF347 and LF347B and from VS = ±20V to ±5V for the LF147.

(1) Unless otherwise specified the specifications apply over the full temperature range and for VS=±20V for the LF147 and for VS=±15V for
the LF347B/LF347. VOS, IB, and IOS are measured at VCM=0.
(2) Refer to RETS147X for LF147D and LF147J military specifications.
