DATA SHEET MOS INTEGRATED CIRCUIT 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. FEATURES • +3 V single power supply • Low power consumption In operation: 7 mA (TYP.) (VDD = 3 V) In stand-by mode: 50 µA (TYP.) (VDD = 3 V) • CODEC • 13-bit precision linear coding • Transmission level can be controlled by microcontroller.
