L6726 UNIVERSAL SPEECH CIRCUIT

The UTC L6726 is a mask-programmable, monolithic integrated speech circuits for using in electronic telephones. It is designed for using with a low impedance microphone. Transmitting and receiving gain are regulated with line length. Different regulation for various current feeds can be set by exter.
