DC ELECTRICAL CHARACTERISTICS The l denotes the specications which apply over the full
operating temperature range, otherwise specications are at TA = 25°C. V+ = 3V, V– = 0V, VCM = VOCM = VICM = 1.25V, VSHDN = open,
RBAL = 100kΩ, RI = 150Ω, RF = 150Ω (0.1% resistors), CF = 1.8pF (see Figure 1) unless otherwise noted. VS is dened as (V+ – V–).
VOUTCM is dened as (V+OUT + V–OUT)/2. VICM is dened as (V+IN + V–IN)/2. VOUTDIFF is dened as (V+OUT – V–OUT).
