Note 1:
Limits over temperature are guaranteed by design.
Note 2:
No output phase-reversal for input common-mode voltage range from GND to V
CC
. Common-mode range limited by voltage
drop across Q1 and RG3.
Note 3:
Guaranteed by design.
Note 4:
Error dependent on tolerance of RG1, RG2, and RG3. Specified with 0.1% tolerance resistors.
