Overview
INTEGRATED CIRCUITS DATA SHEET TDA1545A Stereo continuous calibration DAC Preliminary specification Supersedes data of March 1993 File under Integrated Circuits, IC01 1997 Sep 04 Philips Semiconductors Preliminary specification Stereo continuous calibration DAC FEATURES • Space saving packages • Low power consumption • Low total harmonic distortion • Wide dynamic range (16-bit resolution) • Continuous calibration concept • Easy application: single 3 to 5.
5 V rail power supply and output- and bias current are proportional to the supply voltage • Fast settling time permits 2×, 4× and 8× oversampling (serial input) or double speed operation at 4× oversampling • Internal bias current ensures maximum dynamic range • Wide operating temperature range of −40 to +85 °C • Compatible with most of the Japanese input formats: time multiplexed, two's complement and TTL • No zero crossing distortion.
ORDERING INFORMATION TYPE NUMBER TDA1545A TDA1545AT TDA1545ATT PACKAGE NAME DIP8 SO8 TSSOP14 DESCRIPTION plastic dual in-line package; 8 leads (300 mil) plastic small outline package; 8 leads; body width 3.
9 mm GENERAL DESCRIPTION TDA1545A The TDA1545A is the first device of a new generation of the digital-to-analog converters which embodies the innovative technique of continuous calibration.
The largest bit-currents are repeatedly generated by one single current reference source.
This duplication is based upon an internal charge storage principle having an accuracy insensitive to ageing, temperature and process variations.
The device is fabricated in a 1.
0 µm CMOS process and features an extremely low power dissipation, small package size and easy application.
Furthermore, the accuracy of the high coarse current combined with the implemented symmetrical offset decoding method preclude zero-crossing distortion and ensures high quality audio reproduction.
Therefore, the continuous calibration digital-to-analog converter is eminently suitable for use in (portable) digital audio equ...
