Preliminary specification
TDA1312A; TDA1312AT
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.
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.
