ELECTRICAL CHARACTERISTICS Test conditions are at TA = +25°C, VS+ = +5V, VOCM = +2.5V, VOUT = 2VPP, RL = 400Ω differential, G = +12dB, differential input and output, and input and output referenced to midsupply, unless otherwise noted. Measured using evaluation module as discussed in Test Circuits section.
