The Philips TDA1540 is a monolithic integrated 14-bit digital-to-analog converter (DAC). It incorporates a 14-bit input shift register with output latches, binary weighted current sources with switches and a reference source.

The IC features an improved switch circuitry which eliminates the need for a deglitcher circuit at the output. This results in a signal-to-noise ratio of typical 85dB in the audio band.
