Product specification

TDA1309H

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.

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.
