ES7144LV
GENERAL DESCRIPTION
The ES7144LV is a low cost 10-pin
stereo digital to analog converter. The
ES7144LV 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.
FEATURES
100 dB SNR
-85 dB THD+N
Up to 200 kHz sampling frequency
I

S audio data format, 16-24 bits
Single power supply 3V to 5.5V
APPLICATIONS
Digital Photo Frame
Set top box
Digital TV
DVD player
Audio player
