LTC6401-20 Datasheet, PDF (3/16 Pages) Linear Technology – 1.3GHz Low Noise, Low Distortion Differential ADC Driver for 140MHz IF

LTC6401-20
DC ELECTRICAL CHARACTERISTICS The ● denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at T_A = 25°C. V⁺ = 3V, V^– = 0V, +IN = –IN = V_OCM = 1.25V, ^⎯E^⎯N^⎯A^⎯B^⎯L^⎯E = 0V, No R_L unless
otherwise noted.
