TDA1545A数据手册恩XP中文资料规格书

描述 Description

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.
