AD1953YSTZ

The AD1953YSTZ is one member of the AD1953 family which designed as the complete 26-bit, single-chip, 3-channel digital audio playback system with built-in DSP functionality for speaker equalization, dual-band compression/limiting, delay compensation, and image enhancement. This device can be used in (1)2.0/2.1 channel audio systems (2 main channels plus subwoofer); (2)multichannel automotive sound systems; (3)multimedia audio; (4)mini component stereo; (5)home theater systems (AC-3 postprocessor); (6)musical instruments; (7)in-seat sound systems (aircraft, motor coaches).

Features of the AD1953YSTZ are:(1)5 V 3-channel audio DAC system;(2)digital audio output (2-channel or 6-channel packed mode);(3)accepts sample rates up to 48 kHz;(4)7 biquad filter sections per channel;(5)dual dynamic processor with arbitrary input/output curve and adjustable time constants;(6)0 ms to 6 ms variable delay/channel for speaker alignment;(7)parameter RAM allows complete control of more than 200 parameters via SPI port;(8)SPI port features safe-upload mode for transparent filter updates;(9)2 control registers allow complete control of modes and memory transfers;(10)48-lead LQFP plastic package;(11)graphical custom programming tools;(12)auxiliary digital input;(13)hardware and software controllable clickless mute.

The absolute maximum ratings of the AD1953YSTZ can be summarized as:(1)DVDD to DGND:-0.3 V to +6 V;(2)ODVDD to DGND:-0.3 V to +6 V;(3)AVDD to AGND:-0.3 V to +6 V;(4)digital inputs:DGND-0.3 V to DVDD+0.3 V;(5)analog inputs:AGND-0.3 V to AVDD+0.3 V;(6)AGND to DGND:-0.3 V to +0.3 V;(7)refere-nce voltage:(AVDD + 0.3)/2 V;(8)maximum junction temperature:125;(9)storage temperature range:-65 to +150;(10)soldering:300/10 sec.
