Description
The programmable telephone audio processor U4091BM-N is a linear integrated cir-
cuit 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 nec-
essary for signal amplification and adaptation to the line. The U4091BM-N can also be
supplied via an external power supply. An integrated voice switch with loudspeaker
amplifier enables hands-free or loudhearing operation. With an anti-feedback function,
acoustic feedback during loudhearing can be reduced significantly. The generated
supply voltage is suitable for a wide range of peripheral circuits.
