Electrical Specifications
Unless Otherwise Specified, TA = -40oC to 85oC for industrial (I) grade and TA = 0oC to 85oC for commercial
(C) grade, VBL = -24V, VBH = -100V, -85V or -75V, VCC = +5V, AGND = BGND = 0V, loop current limit = 25mA.
All AC parameters are specified at 600Ω 2-wire terminating impedance over the frequency band of 300Hz to
3.4kHz. Protection resistors = 0Ω.
