ELECTRICAL CHARACTERISTICS The
l
denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at 0°C ≤ TA ≤ 70°C. VS = ±15V, VCM = 0V. (Note 2)
The l denotes the specifications which apply over the full operating temperature range, otherwise specifications
are at –55°C ≤ TA ≤ 125°C. VS = ±15V, VCM = 0V. (Note 2)
The l denotes the specifications which apply over the full operating temperature range, otherwise specifications
are at –40°C ≤ TA ≤ 85°C. VS = ±15V, VCM = 0V. (Note 6)
