Monolithic 16-Bit ∆Σ ADC and DAC
•
Stereo ADC:
– Single-Ended Voltage Input
– Antialiasing Filter
– 64× Oversampling
Digital Video Cameras
– High Performance
• THD+N: –84 dB
DESCRIPTION
• SNR: 89 dB
The PCM3006 is a low-cost, single-chip stereo audio
codec (analog-to-digital and digital-to-analog con-
verters) with single-ended analog voltage input and
output.
• Dynamic Range: 89 dB
– Digital High-Pass Filter
Stereo DAC:
•
Both ADCs and DACs employ delta-sigma modu-
lation 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 a digital de-emphasis function.
The PCM3006 operates with 16-bit, left-justified for
ADC, right-justified for DAC data formats.
– Single-Ended Voltage Output
– Analog Low-Pass Filter
– 8× Oversampling Digital Filter
– High Performance
• THD+N: –84 dB
• SNR: 93 dB
The PCM3006 provides a power-down mode that
operates on the ADCs and DACs independently.
• Dynamic Range: 93 dB
Special Features
•
The PCM3006 is fabricated using a highly advanced
CMOS process, and is available in a small 24-pin
TSSOP package. The PCM3006 is suitable for a wide
variety of cost-sensitive consumer applications where
good performance is required.
– Digital De-Emphasis
– Power Down: ADC/DAC Independent
Sampling Rate: 4 kHz to 48 kHz
System Clock: 256 fS, 384 fS, 512 fS
Single 3-V Power Supply
Small Package: 24-Lead TSSOP
