Everest Semiconductor ES7154
ES7154
24-bit I2S Audio DAC with 2 Vrms Output
GENERAL DESCRIPTION
The ES7154 is a low cost 14-pin stereo
digital to analog converter. The ES7154 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.
The devices integrates a charge pump to
generate negative supply from 5V supply,
thus providing ground centered 2 Vrms
analog output.
FEATURES
102 dB SNR
-85 dB THD+N
Up to 100 kHz sampling frequency
I2S audio data format, 16-24 bits
Single power supply 4V to 5.25V
Support non standard audio clocks
like 25 MHz or 26 MHz
APPLICATIONS
OTT
STB
Digital TV
DVD player
