Electrical Characteristics: (VS+) – (VS–) = 5 V (continued)
at TA ≈ 25°C, VOCM pin = open, RF = 1 kΩ, RL = 1 kΩ, VOUT = 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);
specifications are per channel; see Figure 61 for a gain of 1-V/V test circuit
