Digital Audio 16-Bit D/A Converter
with Built-In Digital Filters
Overview
The LC78833M and LC78833V are CMOS 16-bit D/A
converters with built-in 4× oversampling digital filters.
Functions and Features
[Digital Filter Block]
• 4× oversampling filters: Two FIR filter stages (33rd and
ninth order)
• De-emphasis filter: Supports a 44.1 kHz sampling
frequency (fs).
[D/A Converter Block]
• Dynamic level shifting conversion 16-bit D/A converter
• D/A converters for two channels (synchronized outputs)
on a single chip
• On-chip output operational amplifiers
• System clock: 384fs
• 5-V single-voltage power supply
• Supports low-voltage operation (3.0 V)
• Implemented in a Si gate CMOS process for low power.
