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 dissipation, small package size and easy application. Furthermore, the accuracy of the intrinsic high coarse-current combined with the implemented symmetrical offset decoding method preclude zero-crossing distortion and ensures high quality audio reproduction. Therefore, the CC-DAC is eminently suitable for use in (portable) digital audio equipment. PACKAGE EXTENDED TYPE NUMBER PINS TDA1312A(1) TDA1312AT(2) Notes 1. SOT97-1; 1996 August 14. 2.

A symmetrical offset decoding principle is incorporated and arranges the bit switching in such a way that the zero-crossing is performed only by switching the LSB currents. The TDA1312A; AT (CC-DAC) accepts serial input data formats of 16-bit word length. Left and right data words are time multiplexed. The most significant bit (bit 1) must always be first. The input data format is shown in Figs.4 and 5. Data is placed in the right and left input registers (see Fig.1). The data in the input registe.
