STEREO AUDIO D/A

CONVERTER 24BITS,96KHZ

SAMPLING

DESCRIPTION

The UTC M4334 is a complete low cost stereo audio digital to

analog converter(DAC), its contains interpolation, 1-bit D/A conversion

and analog output filtering. The M4334 is based on a 4th order Δ-Σ

modulation, where the modulator output controls the reference voltage

input to an ultra-liner analog low-pass filter. This architecture allows

for infinite adjustment of sample rate between 2 kHz and 100 kHz

simply by changing the master clock frequency.

The M4334 also contains digital de-emphasis function, operates

from a single +5V power supply, for best performance, decoupling

capacitors should be located as close to the device package as

possible with the smallest capacitor closest,

the M4334 requires

minimal support circuitry.

The M4334 is ideal for DVD players, set-top boxes, SVCD

players and A/V receivers.
