AC ELECTRICAL CHARACTERISTICS The l denotes the specications which apply over the full operating
temperature range, otherwise specications are at TA = 25°C. V+ = 3V, V– = 0V, SHDN = 2V, +IN is shorted to +TERM, –IN is shorted to
–TERM, VINCM = VBIAS = 1.5V, input source resistance (RS) is 25Ω on each input (50Ω differential), RL = 50Ω from +OUT to –OUT, +IN
and –IN are AC-coupled, unless otherwise noted. VBIAS is dened as the voltage on theVBIAS pin. VOUTCM is dened as
(+OUT + –OUT)/2. VINCM is dened as (+IN + –IN)/2. VINDIFF is dened as (+IN – –IN). VOUTDIFF is dened as (+OUT – –OUT).
