Receive Attenuator Gain (f = 1.0 kHz, VLC = VB)
Rx Mode, RXI = 150 mVrms (Vcc = 5.0V)
Rx Mode, RXI = 150 mVrms (Vcc = 3.5V)
Gain Change – Vcc = 3.5V versus Vcc = 5.0V
AGC Gain Change – Vcc = 2.8V versus Vcc = 5.0V
Idle Mode, RXI = 150 mVrms
Range (Rx to Tx mode)
Volume Control Range (Rx Mode, 0.3VB < VLC < VB)
RXO DC Voltage (Rx Mode)
∆RXO
DC Voltage (Rx to Tx Mode)
RXO High Voltage (Iout = - 1.0mA RXI = VB + 1.5V)
