TECHNICAL DATA Universal Speech Circuit with Dialler Interface IL3726AN The IL3726AN is a low voltage speech network which includes Mic amp. transmit amp, receive amp. and stabilized DC-supply It handles the voice signal performing the 2/4 wire interface and changing the gain on both sending and receiving amplifiers to compensate for line attenuation by sensing thelinelengththrough the line current. Application dependent parameters such as amplitude of each amp, sidetone level, line balance and frequency response are controlled by external components. Each gain can be controlled by external component exchange. ORDERING INFORMATION IL3726AN TA = -40° to 70° C • Uses a minimum of external components (7 Capacitors & 11 Resistors) • Low Voltage Operating • Symmetrical inputs for microphones, provided good balance to ground • DTMF signal input with confidence tone • Mute input for DTMF dialling • Line loss compensation (line current dependent) for microphone and earpiece amplifiers • Gain control curve adaptable to exchange supply www.DataSheet4U.com• DC line voltage adjustment facility BLOCK DIAGRAM 789 DC 12 13 6 14 17 18 10 53 11 2 15 14 16 1 1 page
