PCM1717E

ADCs/DACs - Special Purpose Overview

The PCM1717E is a stereo audio digital-to-analog converter fabricated on a 0.6 μm CMOS process. It accepts 16- or 18-bit input data in normal or I2S formats and operates with system clocks of 256fs or 384fs. The device integrates an 8x oversampling digital filter, a multi-level delta-sigma DAC, analog output amplifiers, and low-pass filters. Key electrical specifications include a typical signal-to-noise ratio of 100 dB, dynamic range of 96 dB, and THD+N of -90 dB at +5V supply. It supports a wide power supply range from +2.7V to +5.5V and features selectable soft mute, digital attenuation, and de-emphasis functions within a compact SSOP-20 package.
