INTEGRATED CIRCUITS DATA SHEET TDA1547 Dual top-performance bitstream DAC Product specification File under Integrated Circuits, IC01 September 1991 Philips Semiconductors Product specification Dual top-performance bitstream DAC Features - Top-grade audio performance - very low harmonic distortion - high signal-to-noise ratio - wide dynamic range of approximately 108 d B (not A-weighted) - High crosstalk immunity - Bitstream concept - high over-sampling rate up to 192 fs - pulse-density modulation - inherently monotonic - no zero-crossing distortion GENERAL DESCRIPTION The TDA1547 is a dedicated one-bit digital-to-analog converter to facilitate a high fidelity sound reproduction of digital audio. The TDA1547 is extremely suitable for use in high quality audio systems such as pact Disc and DAT players, or in digital amplifiers and digital signal processing systems. The TDA1547 is used in bination with the SAA7350 bitstream circuit, which includes the ORDERING INFORMATION EXTENDED TYPE NUMBER TDA1547(1) Note 1. SOT-232-1; 1996 August 23. PACKAGE PINS 32 PIN POSITION SDIL MATERIAL plastic TDA1547 third-order noise shaper. The excellent performance of the SAA7350 and TDA1547 bitstream conversion system is obtained by separating the noise shaping circuit and the one-bit conversion circuit over two IC's, thereby reducing the crosstalk between the digital and analog parts. The TDA1547 one-bit converter is processed in BIMOS. In the digital logic and drivers bipolar transistors are used to optimize speed and to reduce digital noise generation. In the analog part the bipolar transistors are used to obtain high performance of the operational amplifiers. Special layout precautions have been taken to achieve a high crosstalk immunity. The layout of the TDA1547 has fully separated left and right channels and supply voltage lines between the digital and analog sections.
