ac electrical characteristics The
l
denotes the specifications which apply over the full
operating temperature range, otherwise specifications are at TA = 25°C. V+ = 5V, V– = 0V, VCM = VOCM = VICM = 2.5V, VSHDN = open,
RLOAD = 400Ω, circuit component values in Figure 2 used, unless otherwise noted. VS is defined as (V+ – V–). VICM is defined as (V+IN
+ V–IN)/2. VOUTDIFF is defined as (V+OUT – V–OUT).
