PA5144

24-Bit, 192 kHz Stereo D/A Converter

for PCM Audio

ANALO G P RO DUCTS DIVIS IO N

FEATURES

GENERAL DESCRIPTION



95 dB dynamic range

-85 dB THD+N

Up to 200 kHz sampling frequency

I²S audio data format, 16-24 bits

Single power supply 4.5 V to 5.5V

The PA5144 is a low cost 10-pin stereo digital to analog

converter.

The PA5144 can accept I²S serial audio data format up to 24-

bit word length.

The device uses advanced multi-bit ∆-∑ modulation technique

to convert data into two channel analog outputs.

APPLICATIONS



DVD players

The multi-bit ∆-∑ modulator makes the device with very low

sensitivity to clock jitter and very low out of band noise.

Portable audio players

Set top boxes

Digital TVs
