The SM5803AP is a multi-function digital filter for digital audio fabricated using NPC's original molybdenum-gate CMOS technology.
There are some features of the SM5803AP as follows:
(1)Noise shaper (can be turned on or off) reduction of requantization noise component in the audio band;
(2)High-precision operation by 25-bit accumulator;
(3)Digital attenuation;
(4)Soft mute: smooth changes of attenuation level;
(5)Built-in overflow limiter;
(6)Digital attenuation;
(7)Built-in quartz oscillator circuitry.
The absolute maximum ratings of the SM5803AP can be summarized as follows:
(1)Soldering temperature: 255 ℃;
(2)Soldering time: 10 sec;
(4)power dissipation:250 mW;
(3)Storage temperature range:-40 to 125℃;
(5)Supply voltage:-0.3 to 7.0V;
(6)Input voltage:-0.3 to Vdd+0.3V.
