4 / 23 page TS34118 Voice Switched Speakerphone Circuit 4/23 Version: A08 Electrical Characteristics - Continue Parameter Symbol Min Typ Max Unit Filter (TA=+25ºC) Voltage offset at FO (VFO-VB, 220KΩ from VB to FI) FOVOS -200 -90 0 mV FO sink current IFO 150 260 400 µA FI bias current IFI -- -50 -- nA System Distortion (TA=+25ºC, f=1.0KHz) Rx mode (from FI to RXO, FO connected to RXI) THDR -- 0.5 3.0 % Tx mode (from MCI to HTO-/HTO+, includes Tx attenuator) THDT -- 0.8 3.0 % * All currents into a device pin are positive, those out of a pin are negative. Algebraic convention rather than magnitude is used to define limits.
