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+, RL = Open,

RBAL = 10k. The filter is configured for a gain of 1, unless otherwise noted. VS is defined as (V+ – V–). VOUTCM is defined as (V+OUT +

V–OUT)/2. VINCM is defined as (VINP + VINM)/2. VOUTDIFF is defined as (V+OUT – V–OUT). VINDIFF is defined as (VINP – VINM). See Figure 1.
