DC ELECTRICAL CHARACTERISTICS The l denotes specications that apply over the full operating
temperature range, otherwise specications are at TA = 25°C. DC electrical performance measured using DC test circuit schematic.
VIN(DIFF) is dened as (+IN) – (–IN). VOUT(DIFF) is dened as (+OUT) – (–OUT). VIN(CM) is dened as [(+IN) + (–IN)]/2. VOUT(CM) is
dened as [(+OUT) + (–OUT)]/2. Unless noted otherwise, default operating conditions are VCC = 3.3V, EN = 0.8V, SHDN = 2.2V, +VG tied
to VREF (negative gain slope mode), VOUT(CM) = 3.3V. Differential power gain dened at ZSOURCE = 50Ω differential and ZLOAD = 200Ω
differential.
