l
denotes specifications that apply over the full specified temperature range, otherwise specifications are at TA = 25°C. Unless noted otherwise, V+ = 5V, V– = 0V, V+IN1 = V2 = Mid-Supply, VSHDN = V+, RL = OPEN, RF = SHORT, RG = OPEN. VS is defined as (V+ – V–). VOUTCM is defined as (VOUT1 + VOUT2)/2. VOUTDIFF is defined as (VOUT1 – VOUT2). See Figure 1. SYMBOL PARAMETER CONDITIONS MIN TYP MAX UNITS
