7.9 Typical Characteristics: (VS+) – (VS–) = 3-V to 12-V Supply Range

at TA ≈ 25°C, VOCM pin = open, RF = 1.5 kΩ, RL = 1 kΩ, VO = 2 VPP, 50-Ω input match, G = 1 V/V, PD = VS+, single-ended

input, differential output, and input and output referenced to default midsupply for AC-coupled tests (unless otherwise noted);

see Figure 8-1 for a gain of 1-V/V test circuit.
