FEATURES
• Low distortion
• 16-bit dynamic range
• 4 × oversampling possible
• Single 5 V power supply
• No external components required
• No requirement for external deglitcher circuitry due to
fast settling output current
• Adjustable bias current
• Internal timing and control circuits
• I2S input format: time multiplexed, two's complement,
TTL.

GENERAL DESCRIPTION
The TDA1543 is a monolithic integrated dual 16-bit
digital-to-analog converter (DAC) designed as an
economy version for use in hi-fi digital audio equipment
such as Compact Disc players, digital tape or cassette
recorders, digital sound in TV sets and in digital amplifiers.
