TA = 25°C, +VS = 5 V, −VS = −5 V, VOCM = 0 V, RT = 61.9 Ω, RG = RF = 200 Ω, G = +1, RL, dm = 1 kΩ, unless otherwise noted. All measurements were performed with single-ended input and differential output, unless otherwise noted. For gains other than G = +1, values for RF and RG are shown in Table 11.
