GENERAL DESCRIPTION
The TDA1545A 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.
FEATURES
• Space saving packages
• Low power consumption
• Low total harmonic distortion
• Wide dynamic range (16-bit resolution)
• Continuous calibration concept
• Easy application: single 3 to 5.5 V rail power supply and output- and bias current are proportional to the supply voltage
• Fast settling time permits 2×, 4×and 8× oversampling (serial input) or double speed operation at 4× oversampling
• Internal bias current ensures maximum dynamic range
• Wide operating temperature range of−40 to +85°C
• Compatible with most of the Japanese input formats: time multiplexed, two's complement and TTL
• No zero crossing distortion.
