Electrical Characteristics: VS = 2.7 V (continued)
Test conditions at TA = 25°C, VS+ = 2.7 V, VSâ = 0 V, VOCM = +VS/2, VOUT = 2 VPP, RF = 2 kΩ, RL = 2 kΩ differential, G = 1 V/V,
single-ended input, differential output, and input and output referenced to mid-supply, unless otherwise noted.

Turn-on time delay
Time from PD = high to VOUT = 90% of final
value, RL= 200 Ω
Turn-off time delay
Time from PD = low to VOUT = 10% of original
