Overview
INTEGRATED CIRCUITS DATA SHEET TDA1386T Noise shaping filter DAC Product specification Supersedes data of 1995 Dec 11 File under Integrated Circuits, IC01 1998 Jan 06 Philips Semiconductors Product specification Noise shaping filter DAC FEATURES General • Double-speed mode • Digital volume control • Soft mute function • 12 dB attenuation • Low power dissipation • Digital de-emphasis.
Easy application • Voltage output • Only 1st-order analog post-filtering required • Operational amplifiers and digital filter integrated • 256fs system clock (fsys) • I2S-bus or 16, 18 or 20 bits LSB fixed serial input format • Single rail supply.
High performance • Superior signal-to-noise ratio • Wide dynamic range • No zero crossing distortion • Inherently monotonic • Continuous calibration digital-to-analog conversion combined with noise shaping technique.
ORDERING INFORMATION PACKAGE TYPE NUMBER NAME TDA1386T SO24 DESCRIPTION plastic small outline package; 24 leads; body width 7.
5 mm GENERAL DESCRIPTION TDA1386T The TDA1386T is a dual CMOS digital-to-analog converter with up-sampling filter and noise shaper.
The combination of oversampling up to 4fs, noise shaping and continuous calibration conversion ensures that only simple 1st order analog post filtering is required.
The TDA1386T supports the I2S-bus data input mode with word lengths of up to 20 bits and the LSB fixed serial data input format with word lengths of 16, 18 or 20 bits.
Two cascaded IIR filters increase the sampling rate 4 times.
The DACs are of the continuous calibration type and incorporate a special data coding.
This ensures a high signal-to-noise ratio, wide dynamic range and immunity to process variation and component ageing.
Two on-board operational amplifiers convert the digital-to-analog current to an output voltage.
