low-cost,
The ADCs and DACs employ delta-sigma modulation
with 64-times oversampling. The ADCs include a
digital decimation filter, and the DACs include an
8-times oversampling digital interpolation filter. The
DACs also include digital attenuation, de-emphasis,
infinite zero detection, and soft mute to form a
complete subsystem. The PCM3002 and PCM3003
operate with left-justified (ADC) and right-justified
(DAC) formats, while the PCM3002 also supports
other formats, including the I
2
S data format.
The PCM3002 and PCM3003 provide a power-down
mode that operates on the ADCs and DACs indepen-
dently.
The PCM3002 and PCM3003 are fabricated using a
highly advanced CMOS process, and are available in
a
24-pin
SSOP
package.
