Overview
The PCM1804DBRG4, produced by Texas Instruments, is a high-performance, single-chip stereo A/D converter with fully differential analog voltage input. This component is designed for mid- to high-grade consumer and professional audio applications, offering excellent performance and reliability. It utilizes a precision delta-sigma modulator and includes a linear phase antialias digital filter and a high-pass filter (HPF) to remove dc offset from the input signal. The PCM1804DBRG4 is fabricated using an advanced CMOS process and is available in a small 28-pin SSOP package.
