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, VINCM = VOCM = mid-supply, BIAS tied to V+ or oating,
ILOAD = 0, RBAL = 100k. The lter is congured for a gain of 1 unless otherwise noted. VS is dened as (V+ – V–). VOUTCM is dened as
(VOUT+ + VOUT–)/2. VINCM is dened as (VINP + VINM)/2. VOUTDIFF is dened as (VOUT+ – VOUT–). VINDIFF is dened as (VINP – VINM). See
