ES7144

ES7144 10-pin, 24-Bit, 192 kHz Stereo D/A Converter for PCM Audio GENERAL DESCRIPTION FEATURES The ES7144 is a low cost 10-pin stereo digital to analog converter. The ES7144 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.  95 dB dynamic range  -85 dB THD+N  Up to 200 kHz sampling frequency  I2S audio data format, 16-24 bits  Single power supply 4.5V to 5.5V APPLICATIONS  Digital Photo Frame  Portable audio player  Set top box  Digital TV ORDERING INFORMATION ES7144 -40°C ~ +85°C TSSOP-10 BLOCK DIAGRAM SDATA SCLK LRCK Audio Data Interface Clock Manager/ Sample Rate Detector Interpolation Filter Interpolation Filter Multi-level Sigma-delta DAC Multi-level Sigma-delta DAC Output Amp Low Pass Filter Output Amp Low Pass Filter CLKIN AOUTL AOUTR Rev 2.0 1 December, 2010 Everest Semiconductor 1.
