UPD6376

DATA SHEET MOS INTEGRATED CIRCUIT µPD6376 AUDIO 2-CHANNEL 16-BIT D/A CONVERTER The µPD6376 is an audio 2-channel 16-bit D/A converter. The µPD6376 has low sound quality deterioration by employing the resistor string configuration and 0-point offset, and low power consumption by using the CMOS process. It operates on a single 5-V power supply, and it is pincompatible with the µPD6372 when Pin 1 is low level or open. FEATURES Single 5-V power supply CMOS structure On-chip output operational amplifier circuit On-chip 0-point offset circuit Resistor string configuration 8 fS (2 ch × 400 kHz) supported On-chip 2-channel DAC L-R in-phase output ORDERING INFORMATION Part Number Package 16-pin plastic SOP (300 mil) µPD6376GS The information in this document is subject to change without notice.
