ELECTRICAL CHARACTERISTICS The l denotes the specications which apply over the specied temperature
range, otherwise specications are at TA = 25°C. VS = ±15V, VCM = OV, VOUT = OV, unless otherwise noted. (Note 4)
The
l denotes the specications which apply over the full operating temperature range of –40°C ≤ TA ≤ 125°C.
VS = 3V, 0V; VS = 5V, 0V; VCM = VOUT = Half Supply unless otherwise specied. (Note 4)
