GENERAL DESCRIPTION
The TDA1311A; AT is a voltage-driven digital-to-analog converter and is new generation of DAC devices which embodies the innovative technique of Continuous Calibration (CC). The largest bit-currents are repeatedly generated by one single current reference source. This duplication is based upon an internal charge storage principle which has an accuracy insensitive to ageing, temperature matching and process variations.

FEATURES
• Voltage output
• Space saving packages SO8 or DIP8
• Low power consumption
• Wide dynamic range (16-bit resolution)
• Continuous Calibration (CC) concept
• Easy application:
– single 4 to 5.5 V rail supply
– output current and bias current are proportional to the supply voltage
– integrated current-to-voltage converter
• 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 (−40 °C to +85 °C)
• Compatible with most current Japanese input formats: time multiplexed, two's complement, TTL
• No zero-crossing distortion
• Cost efficient.
