GENERAL DESCRIPTION

The TDA1309H is a single chip stereo analog-to-digital and digital-to-analog converter employing bitstream conversion techniques. The low voltage requirement makes the device eminently suitable for use in low-voltage low-power portable digital audio equipment which incorporates recording and playback functions.

FEATURES

? Low power

? Low supply voltage (2.7 V)

? Integrated high-pass filter to cancel DC offset (ADC)

? Analog loop-through function

? Multiple digital input/output formats possible

? 256fs system clock frequency

? Several power-down modes

? Digital de-emphasis (DAC)

? Overload detector to enable automatic recording level adjustment (ADC)

? Input pads suitable for 5.5 V; low supply voltage interfacing

? High dynamic range

? DAC requires only one capacitor for post-filtering

? Small 44-pin quad flat pack with 0.8 mm pitch

? 256fs system clock frequency in Analog-to-Digital (AD) and Digital-to-Analog (DA) mode

? Choice of three system clock frequencies (192fs, 256fs or 384fs) in DA mode.

APPLICATION

? Portable digital audio equipment.
