, 2-channel D/A Converter
OVERVIEW
The SM5876AM is a 3rd-order
converter LSI for CD-ROM digital audio reproduc-
tion equipment. It incorporates an 8-times oversam-
pling digital filter, deemphasis filter, attenuator, and
soft mute circuits built-in., using NPC’s Molybde-
num-gate CMOS technology.
Σ
, 2-channel D/A
The SM5876AM operates from a 2.7 to 5.5 V supply,
and is available in 24-pin SSOPs.
