STEREO AUDIO CODECs  
FEATURES  
DESCRIPTION  
MONOLITHIC 20-BIT ∆Σ ADC AND DAC  
16-/20-BIT INPUT/OUTPUT DATA  
SOFTWARE CONTROL: PCM3002  
HARDWARE CONTROL: PCM3003  
The PCM3002 and PCM3003 are low cost single chip  
stereo audio CODECs (analog-to-digital and digital-to-  
analog converters) with single-ended analog voltage  
input and output.  
The ADCs and DACs employ delta-sigma modulation  
with 64X oversampling. The ADCs include a digital  
decimation filter, and the DACs include an 8X  
oversampling digital interpolation filter. The DACs  
also include digital attenuation, de-emphasis, infinite  
zero detection and soft mute to form a complete  
subsystem. PCM3002 and PCM3003 operate with  
left-justified, and right-justified formats, while the  
PCM3002 also supports the I2S data format.  
STEREO ADC:  
Single-Ended Voltage Input  
64X Oversampling  
High Performance  
THD+N: –86dB  
SNR: 90dB  
Dynamic Range: 90dB  
STEREO DAC:  
Single-Ended Voltage Output  
Analog Low Pass Filter  
64X Oversampling  
High Performance  
THD+N: –86dB  
PCM3002 and PCM3003 provide a power-down mode  
that operates on the ADCs and DACs independently.  
Fabricated on a highly advanced CMOS process,  
PCM3002 and PCM3003 are suitable for a wide vari-  
ety of cost-sensitive consumer applications where good  
performance is required.  
SNR: 94dB  
Dynamic Range: 94dB  
SPECIAL FEATURES  
Digital De-emphasis  
PCM3002’s programmable functions are controlled  
by software and the PCM3003’s functions include de-  
emphasis, power down, and audio data format selec-  
tions, which are controlled by hardware.  
Digital Attenuation (256 Steps)  
Soft Mute  
Digital Loop Back  
Power Down: ADC/DAC Independent  
SAMPLING RATE: Up to 48kHz
