Atmel U4091BM-R Programmable Telephone Audio Processor DATASHEET ● Speech circuit with anti-clipping ● Tone-ringer interface with DC/DC converter ● Speaker amplifier with anti-distortion ● Power-supply management regulated and unregulated and a special supply for electret microphone ● Voice switch ● Interface for answering machine and cordless phone ● Feature phone ● Answering machine ● Fax machine ● Speaker phone ● Cordless phone ● No piezoelectric transducer necessary for tone ringing ● Complete system integration of analog signal processing on one chip ● Very few external components The programmable telephone audio processor U4091BM-R is a linear integrated circuit for use in feature phones, answering machines and fax machines. It contains the speech circuit, tone-ringer interface with DC/DC converter, sidetone equivalent and ear-protection rectifiers. The circuit is line-powered and contains all components necessary for signal amplification and adaptation to the line. The Atmel U4091BM-R can also be supplied via an external power supply. An integrated voice switch with loudspeaker amplifier enables hands-free or open-listening operation. With an anti-feedback function, acoustic feedback during open listening can be reduced significantly. The generated supply voltage is suitable for a wide range of peripheral circuits.
