7.5 Electrical Characteristics: VS+ – VS– = 5 V to 12 V (continued)

at TA ≈ 25°C, VOCM(1) = midsupply, differential output (VO) = VOUT+ – VOUT– = 2 VPP, RF = 1.5 kΩ, RL = 1 kΩ, 50-Ω input

match, differential closed-loop gain (G) = 1 V/V, single-ended input (SE-in), differential output (diff-out), and input and output

referenced to midsupply for AC-coupled tests (unless otherwise noted)
