DESCRIPTION

The PCM1804 is a high-performance, single-chip

stereo A/D converter with fully differential analog

–

Pass-Band Ripple: ±0.005 dB

Stop-Band Attenuation: –100 dB

voltage input. The PCM1804 uses

a precision

delta-sigma modulator and includes a linear phase

antialias digital filter and high-pass filter (HPF) that

removes dc offset from the input signal. The

PCM1804 is suitable for a wide variety of mid- to

high-grade consumer and professional applications,

where excellent performance and 5-V analog supply

and 3.3-V digital power-supply operation are required.

The PCM1804 can achieve both PCM audio and

DSD format due to the precision delta-sigma

modulator. The PCM1804 is fabricated using an

advanced CMOS process and is available in a small

28-pin SSOP package.

•

Fully Differential Analog Input: ±2.5 V

Audio Interface: Master- or Slave-Mode

Selectable

Data Formats: Left-Justified, I²S, Standard

24-Bit, and DSD

•

Function:

–

Peak Detection

High-Pass Filter (HPF): –3 dB at 1 Hz,

f_S= 48 kHz

•

Sampling Rate up to 192 kHz

System Clock: 128 f_S, 256 f_S, 384 f_S,

512 f_S, or 768 f_S

•

Dual Power Supplies:

–

5 V for Analog

3.3 V for Digital

•

Power Dissipation: 225 mW

Small 28-Pin SSOP

DSD Output: 1 Bit, 64 f_S
