TDA1386T is a double-speed mode noise shaping filter DAC with features like digital volume control, soft mute function, low power dissipation, and digital de-emphasis. It supports I2S-bus or 16, 18 or 20 bits LSB fixed serial input format and has high performance characteristics such as superior signal-to-noise ratio, wide dynamic range, and no zero crossing distortion.
The TDA1386T is a dual CMOS digital-to-analog converter (DAC) featuring an integrated up-sampling filter and noise shaper. It supports 2S-bus data input modes with word lengths of up to 20 bits and LSB fixed serial formats, requiring only simple first-order analog post-filtering for high-performance audio conversion.
The device incorporates two on-board operational amplifiers that convert the digital-to-analog current to an output voltage. It offers features such as double-speed mode, digital volume control, soft mute function, and digital de-emphasis, operating from a single rail supply.
