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 = mid-supply, VSHDN = OPEN,
RI = RF = 499Ω, RL = 800Ω to a mid-supply voltage (See Figure 1) unless otherwise noted. VS is dened (V+ – V–). VOUTCM is dened
as (VOUT+ + VOUT–)/2. VICM is dened as (VIN+ + VIN–)/2. VOUTDIFF is dened as (VOUT+ – VOUT–). VINDIFF is dened as (VIN+ – VIN–).
