124-dB Professional 2-Channel ADC<br />
PCM4222<br />
www.ti.com/sc/device/PCM4222<br />
<strong>Audio</strong> ADCs are used in applications ranging from portable MP3 player<br />
docking stations to professional multichannel mixing consoles.<br />
The PCM4222 is TI’s next-generation audio ADC and offers the best<br />
performance with the lowest power consumption in the industry.<br />
With modulator, PCM and DSD outputs, the PCM4222 enables<br />
superior design flexibility. TI’s advanced silicon technology provides<br />
124 dB of dynamic range with only 305 mW of power consumption,<br />
enabling multiple channels without consuming the entire system’s<br />
heat budget. Added functionality such as TDM ports also supports<br />
multichannel designs.<br />
Key Features<br />
• 124-dB dynamic-range output makes this the world’s highest<br />
performance ADC<br />
• Multiple format output (modulator, DSD and PCM) allowing<br />
development of custom digital filters<br />
• 124-dB 6-bit modulator output<br />
• 123-dB DSD output<br />
• 123-dB PCM output<br />
• Multichannel TDM mode enables flexibility in system partitioning<br />
• 305 mW power consumption at 48 kHz<br />
Applications<br />
• Mixing consoles<br />
• Musical instruments<br />
• High-end AV<br />
• <strong>Audio</strong> recording equipment<br />
• Live-audio broadcasts<br />
