Product Summary

The TDA1545AT/N2 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 TDA1545AT/N2 is fabricated in a 1.0 mm 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 TDA1545AT/N2 is eminently suitable for use in (portable) digital audio equipment.

Parametrics

TDA1545AT/N2 absolute maximum ratings: (1)VP positive supply voltage: 6 V; (2)Txtal(max) maximum crystal temperature: +150 ℃; (3)Tstg storage temperature: -55 to +150 ℃; (4)Tamb operating ambient temperature: -40 to +85 ℃; (5)Ves electrostatic handling: -2000 to +2000 V.

Features

TDA1545AT/N2 features: (1)Space saving packages; (2)Low power consumption; (3)Low total harmonic distortion; (4)Wide dynamic range (16-bit resolution); (5)Continuous calibration concept; (6)Easy application: single 3 to 5.5 V rail power supply and output- and bias current are proportional to the supply voltage; (7)Fast settling time permits 2, 4 and 8 oversampling (serial input) or double speed operation at 4 oversampling; (8)Internal bias current ensures maximum dynamic range; (9)Wide operating temperature range of -40 to +85 ℃; (10)Compatible with most of the Japanese input formats: time multiplexed, two complement and TTL; (11)No zero crossing distortion.
