PA5144LV
24-Bit, 192 kHz Stereo D/A Converter
for PCM Audio
GENERAL DESCRIPTION
The PA5144LV is a low cost 10-pin stereo digital to analog
converter.
The PA5144LV 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.
The multi-bit ∆-∑ modulator makes the device with very low
sensitivity to clock jitter and very low out of band noise.
