Digital Audio D/A Converter IC
with On-Chip Digital Filters
Overview
The LC78857V is a sigma-delta type D/A converter for
use in digital audio systems. It provides both digital and
analog filters on chip.
Features
• Built-in 8x oversampling digital filters: 3-stage FIR
structure (31st order, 11th order, and 3rd order filters)
• Analog low-pass filter
• Digital deemphasis (handles Fs = 44.1 kHz operation)
• Digital attenuator
• Soft muting
• Supports a 384fs system clock rate.
• 5-V single-voltage power supply
• Fabricated in a silicon gate CMOS process.
