ET4344

Etek Microelectronics ET4344 10-pin, 24-Bit, 192kHz Stereo D/A Converter General Description The ET4344 family members are complete, stereo digital-to-analog output systems including interpolation,multi-bit D/A conversion and output analog filtering in a 10-pin package. The ET4344/5/6/8 support all major audio data interface formats, and the individual devices differ only in the supported interface format. The ET4344 family is based on a fourth order multi-bit delta-sigma modulator with a linear analog low-pass filter. This family also includes auto-speed mode detection using both sample rate and master clock ratioas a method of auto-selecting sampling rates between 2kHz and 200kHz. The ET4344 family contains on-chip digital de-emphasis, operates from a single +3.3V or +5V power supply, and requires minimal support circuitry. These features are ideal for DVD players & recorders, digital televisions, home theater and set top box products, and automotive audio systems. The ET4344 family is available in a 10-pin MSOP package in both Commercial (-10 to +85 °C) and Automotive grades (-40 to +85 °C).
