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 pin-
compatible 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
