3.6V ELECTRICAL CHARACTERISTICS The l denotes the specications which apply over the full
operating temperature range, otherwise specications are at TA = 25°C. V+ = 3.6V, GND = 0V, No RLOAD, CLOAD = 6pF. VCM = 1.25V,
CLHI = V+, CLLO = 0V unless otherwise noted. VINCM is dened as (IN+ + IN–)/2. VOUTCM is dened as (OUT+ + OUT–)/2. VINDIFF is
dened as (IN+ – IN–). VOUTDIFF is dened as (OUT+ – OUT–). See DC test circuit schematic.
