Electrical Specifications
Unless Otherwise Specified, T_A = -40^oC to 85^oC for industrial (I) grade and T_A = 0^oC to 85^oC for commercial
(C) grade, V_BL = -24V, V_BH = -100V, -85V or -75V, V_CC = +3.3V, AGND = BGND = 0V, loop current limit =
25mA. All AC transmission parameters are specified at 600W 2-wire terminating impedance over the frequency
band of 300Hz to 3.4kHz. Protection resistors = 0W. (Continued)
