IL3726AN General Description


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 the line length through 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.

IL3726AN Maximum Ratings

Symbol Parameter Min Max Unit
VLN Positive line voltage, tp = 2s 0 18 V
Iline Line current continious 0 130 mA
Tstg Storage temperature -55 +125 C
TJ Operating temperature range -40 +70 C

IL3726AN Features

• Uses a minimum of external components (7 Capacitors & 11 Resistors)
