Notes:
1. AB = Voltage between the Ai (Tip) and Bi (Ring) pins.
V
2. Overload level is defined when THD = 1%.
3. Guaranteed by design.
4. Not tested in production. Parameter is guaranteed by characterization or correlation to other tests.
5. Layout should have less than 10 pF from pin to ground.
6. IIMT = current coming out from IMT pin.
7. When On Hook, RLDC is open circuit, RLAC = 600 Ω.
8. C3 and C2 have pull-downs and C1 has pull-up to set the device state to Disconnect when the pins are floating.
