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, RL = OPEN, RBAL = 100k (See Figure 1). For the LTC6404-1: RI = 100Ω, RF = 100Ω. For the LTC6404-2: RI = 100Ω,
RF = 200Ω. For the LTC6404-4: RI = 100Ω, RF = 402Ω, unless otherwise noted. VS is dened (V+ – V–). VOUTCM = (VOUT+ + VOUT–)/2.
VICM is dened (VIN+ + VIN–)/2. VOUTDIFF is dened (VOUT+ – VOUT–). VINDIFF = (VINP – VINM)
