3 V for Digital • Power Dissipation: 225 mW • Small 28-Pin SSOP • DSD Output: 1 Bit, 64 fS APPLICATIONS • AV Amplifier • MD Player • Digital VTR • Digital Mixer • Digital Recorder DESCRIPTION The PCM1804-Q1 device is a high-performance, single-chip stereo A/D converter with fully differential analog voltage input which uses a precision deltasigma modulator and includes a linear-phase antialias digital filter and high-pass filter (HPF) that removes DC offset from the input signal.
The PCM1804-Q1 device is suitable for a wide variety of mid- to highgrade consumer and professional applications, where excellent performance and 5-V analog supply and 3.
3-V digital power-supply operation are required.
The PCM1804-Q1 device can achieve both PCM audio and DSD format due to the precision deltasigma modulator.
The PCM1804-Q1 device is fabricated using an advanced CMOS process and is available in a small 28-pin SSOP package.
