SM5840JS

The SM5840JS is an 8-times oversampling digital filter for digital audio,fabricated using NPC's moly-gate CMOS process.It supports 18.9 and 37.8 kHz input sample rates for CDI replay,and 37.8 kHz input sample rates for CDI replay ,and 44.1 kHz input sample rate for CD-DA relay.

Features of the SM5840JS are:(1)stereo 8-times oversampling digital filter; (2)three-stage interpolation filters,consisting of 69-tap,13-tap,and 9-tap FIR filters; (3)IIR deemphasis filter for accuiate gain and phase response; (4)19×14-bit multiplier; (5)24-bit accumulator for increased resolution ; (6)digital attenuator and overflow limiter; (7)within ±0.03 dB passband ripple; (8)greater than 55dB stopband attenuation; (9)linear phase (no group delay); (10)16- or 18-bit serial output data; (11)stereo or bilingual mode output; (12)switchable DC output offset; (13)TTL-compatible inputs and outputs ; (14)moly-gate CMOS process ; (15)singel 5V supply ; (16)18-pin plastic DIPs and 22-pin SOPs.

The absolute maximum ratings of the SM5840JS can be summarized as:(1)supply voltage range:-0.3~7.0V; (2)input voltage range:-0.3~Vdd+0.3V; (3)power dissipation:250mW; (4)operating temperature range:-20~80 deg.C; (5)storage temperauture range:-40 to 125 deg.C; (6)soldering temperature:255deg.C; (7)soldering time:10 S.If you want to know more information such as the electrical characteristics, please download the datasheet in www.seekic.com or www.chinaicmart.com.
