TDA1386数据手册恩XP中文资料规格书

描述 Description

GENERAL DESCRIPTION
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.FEATURES
