PBL 38570 is a monolithic integrated speech transmission circuit for use in electronic telephones. It is designed to accomodate either a low impedance dynamic or an electret microphone. A separate input for DTMF dialling tones that is controlled by a mute signal, and a signal summing point at the transmitter input, are available. An internally preset line l.
• Minimum number of external components, 7 capacitors and 11 resistors. Easy adaption to various market needs. Mute control input for operation with DTMF - generator. A separate input for DTMF tones controlled by mute. Transmitter and receiver gain regulation for automatic loop loss compensation. Extended current and voltage range 5 - 130 mA, down to 2 V. Differential microphone input for good balance to ground. Balanced receiver output stage. Stabilized DC - supplies for low current CMOS diallers and electret microphones. 18 - pin DIP and 20 - pin SO packages. Short start up time. Excellent .
