The PCM1807 is high-performance, low-cost, single-chip stereo analog-
to-digital converter with single-ended analog voltage input. The PCM1807
uses a delta-sigma modulator with 64x oversampling and includes a
digital decimation filter and a high-pass filter that removes the dc
component of the input signal.
Key Features
• Dynamic range/SNR: 99 dB
• THD+N: –93 dB
• Selectable oversampling frequency: 64 f
S
• Stop-band attenuation: –65 dB
• On-chip high-pass filter: f
c
= 0.91 Hz (at 48 kHz)
• Optimized feature for covering general audio end equipment
• Cost-effective standard audio ADC
• Anti-aliasing filter integrated on analog inputs
• Best cost vs. performance compared to competitors’ products
• Packaging: Small 14-pin TSSOP
Applications
• DVD recorder
• AV receiver/amplifier, home theater
• TV, STB
• Car AV (navigation, HDD, etc.)
