ELECTRICAL CHARACTERISTICS The l denotes the specications which apply over the full operating
temperature range, otherwise specications are at TA = 25°C. Single supply operation VS = 5V, 0V; VCM = VS/2 unless otherwise noted.

The
l denotes the specications which apply over the full operating temperature range, otherwise specications are at TA = 25°C.
Split supply operation VS = ±15V, VCM = 0V unless otherwise noted. (Note 5)
