CI TDA1545A

Philips Semiconductors
Stereo continuous calibration DAC TDA1545A
GENERAL DESCRIPTION
The TDA1545A is the first device of a new generation of
the digital-to-analog convertors 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 convertor is eminently suitable for use in
(portable) digital audio equipment.
