詳細說明
GENERAL DESCRIPTION The TDA1387T is a member of a generation of digital-to-analog converters which incorporates the innovative technique of Continuous Calibration. The largest bit currents are repeatedly generated from one single reference current. This duplication is based upon an internal charge storage principle and has an accuracy which is insensitive to ageing, temperature and process variations.FEATURES • Low power consumption • Low total harmonic distortion • Wide dynamic range (16-bit resolution) • Continuous Calibration (CC) concept • Single 3 to 5.5 V supply rail • Output and bias current are proportional to the supply voltage • Fast settling time enables 2, 4 and 8 times oversampling (serial input) or double-speed operation at 4 times oversampling • Internal bias current ensures maximum dynamic range • Wide operating temperature range (−40 to + 85 °C) • I2S-bus input format (time multiplex, two’s complement, TTL) • No zero-crossing distortion • Large DC output voltage compliance • Contained in small outline package.APPLICATIONS • Portable digital audio equipment.
