TDA1312A

INTEGRATED CIRCUITS DATA SHEET TDA1312A; TDA1312AT Stereo continuous calibration DAC (CC-DAC) Preliminary specification File under Integrated Circuits, IC01 July 1993 Philips Semiconductors Preliminary specification Stereo continuous calibration DAC (CC-DAC) FEATURES 8 × oversampling (simultaneous input) possible Voltage output Space saving package SO8 or DIL8 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 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 and TTL No zero-crossing distortion Cost efficient. ORDERING INFORMATION TDA1312A; TDA1312AT GENERAL DESCRIPTION The TDA1312A; 1312AT is a voltage driven D/A converter and is a device of a new generation of digital-to-analog converters 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 having an accuracy insensitive to ageing, temperature matching and process variations. The TDA1312A; 1312AT is fabricated in a 1.0 µm CMOS process and features an extremely low power dissi...
