DC ELECTRICAL CHARACTERISTICS The
l
denotes specifi cations that apply over the full operating temperature range, otherwise specifi cations are at TA = 25°C. DC electrical performance measured using DC test circuit schematic. VIN(DIFF) is defi ned as (+IN) – (–IN). VOUT(DIFF) is defi ned as (+OUT) – (–OUT). VIN(CM) is defi ned as [(+IN) + (–IN)]/2. VOUT(CM) is defi ned 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 defi ned at ZSOURCE = 50Ω differential and ZLOAD = 200Ω differential. SYMBOL PARAMETER CONDITIONS MIN TYP MAX UNITS SHDN Pin
