The TDA1543A is a monolithic integrated dual 16-bit digital-to-analog converter(DAC) designed as a low-cost-economy version for use in hi-fi digital audio equipment such as compact disc players, digital tape or cassete recorders, digital sound in television systems and digital amplifiers.
The S6 version is a relaxed version of the TDA1543A. The differences in performance between the S6 selection and the standard version are limited to only three parameters :
1. Low distortion
2. 16-bit dynamic range
3. 4 x oversampling possible
4. Single 5V power supply
5. No external components required
