LTC6404 LTC6404 DC ELECTRICAL CHARACTERISTICS The l denotes the specifi cations which apply overthe full operating temperature range, otherwise specifi cations are at TA = 25°C. V+ = 3V, V– = 0V, VCM = VOCM = VICM = Mid-Supply,VSHDN = OPEN, RL = OPEN, RBAL = 100k (See Figure 1). For the LTC6404-1: RI = 100Ω, RF = 100Ω. For the LTC6404-2: RI = 100Ω,R+–F = 200Ω. For the LTC6404-4: RI = 100Ω, RF = 402Ω, unless otherwise noted. VS is defi ned (V+ – V–). VOUTCM = (VOUT + VOUT )/2.V+–+–ICM is defi ned (VIN + VIN )/2. VOUTDIFF is defi ned (VOUT – VOUT ).
