µPD9930
LINEAR CODEC FOR DIGITAL CELLULAR TELEPHONE
The µPD9930 is a +3 V single power operation, low power consumption linear CODEC LSI developed for digital cellular telephone use. CODEC has a wide dynamic use. This IC also Features a microphone/receiver amplifier, a tone generator, DAI (Digital Audio Interface: conforming to GSM11.10), and a power-saving function. These functions can be controlled by microcontroller. In addition, 21 mW (TYP.) low power consumption is enabled during 3 V operation.
