ELECTRICAL CHARACTERISTICS The ● denotes specifications which apply over the full operating
temperature range of – 40°C ≤ TA ≤ 85°C, otherwise specifications are at TA = 25°C. VS = 3V, 0V; VS = 5V, 0V; VCM = VOUT = half supply
unless otherwise noted. (Note 4)
The ● denotes specifications which apply over the full operating temperature range of – 40°C ≤ TA ≤ 85°C, otherwise specifications are
at TA = 25°C. VS = ±15V, VCM = 0V, VOUT = 0V unless otherwise noted. (Note 4)
