U4050B General Description
The electronic speech circuit U4050B is a linear integrated circuit for use in telephone sets. It replaces the hybrid transformer, sidetone equivalent and ear protection rectifiers.
The circuit is line powered and contains all componentsnecessary for amplification of signals and adaptation to the line. An integrated loudspeaker amplifier allows loudhearing operation.
