PCM1804-Q1 Overview
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.
