U4055B1 - Low-Voltage Electronic Speech Circuit

Download the U4055B1 datasheet PDF. This datasheet also covers the U4055B variant, as both devices belong to the same low-voltage electronic speech circuit family and are provided as variant models within a single manufacturer datasheet.

Description

The U4055B electronic speech circuit is a linear integrated circuit for use in telephone and other line fed terminal equipment.

It replaces the common speech circuit with carbon microphone, hybrid transformer, sidetone equivalent and ear protection rectifiers.
