DC ELECTRICAL CHARACTERISTICS The l denotes the speciﬁcations which apply over the full operating

temperature range, otherwise speciﬁcations are at TA = 25°C. V+ = 3V, V– = 0V, VINCM = VOCM = mid-supply, BIAS tied to V+ or ﬂoating,

ILOAD = 0, RBAL = 100k. The ﬁlter is conﬁgured for a gain of 1 unless otherwise noted. VS is deﬁned as (V+ – V–). VOUTCM is deﬁned as

(VOUT+ + VOUT–)/2. VINCM is deﬁned as (VINP + VINM)/2. VOUTDIFF is deﬁned as (VOUT+ – VOUT–). VINDIFF is deﬁned as (VINP – VINM). See
