LC78836M

Digital Audio 16-bit D/A Converter

with On-Chip Digital Filters

Overview

The LC78836M is a 16-bit CMOS D/A converter that

includes 8× oversampling filters on chip. It is pin

compatible with the LC78835M and LC78835KM.

Functions and Features

Digital Filter Block

• 8× oversampling filters: Three FIR filter stages (33rd-

order, 13th-order, and ninth-order filters)

• De-emphasis filter: Support for 32 kHz, 44.1 kHz, and

48 kHz Fs frequencies

• Soft muting

• Noise shaper

• Supports double-speed operation

D/A Converter Block

• 16-bit dynamic level shifting D/A conversion

• Two D/A converter channels on a single chip

(synchronous outputs)

• On-chip output operational amplifiers

• System clock: Supports 384 fs, 392 fs, 448 fs, and

512 fs clocks
