LT1997-1
ELECTRICAL CHARACTERISTICS The
l
denotes the specifications which apply over the full operating temperature range, –40°C < TA < 85°C for I-grade parts, –40°C < TA < 125°C for H-grade parts, otherwise specifications are at TA = 25°C. Difference Amplifier Configuration, V+ = 5V, V– = 0V, VCM = VOUT = VREF = VREF1 = VREF2 = Mid-Supply. VCMOP is the common mode voltage of the internal op amp.
