Overview
® 49% FPO PCM1712U Stereo Audio DIGITAL-TO-ANALOG CONVERTER FEATURES q 16-BIT RESOLUTION q COMPLETE STEREO DAC: 8X Oversampling Digital Filter Multi-Level Delta-Sigma DAC Analog Low Pass Filter Output Amplifier q HIGH PERFORMANCE: –87dB THD + N 94dB Dynamic Range 98dB SNR q SYSTEM CLOCK: 384fs q SINGLE +5V POWER SUPPLY q ON-CHIP DIGITAL FILTER: Soft Mute and Attenuation Digital De-emphasis Double Speed Dubbing Mode q SMALL 28-PIN SOIC PACKAGE DESCRIPTION The PCM1712 is a complete low cost stereo, audio digital-to-analog converter, including digital interpolation filter, 3rd-order delta-sigma DAC, and analog output amplifiers.
PCM1712 accepts 16-bit normal input data (MSB first, right justified), or 16-bit IIS data (32-bits per word, continuous clock).
The digital filter performs an 8X interpolation function, as well as special functions such as soft mute, digital attenuation, de-emphasis and double-speed dubbing.
PCM1712 is suitable for a wide variety of cost-sensitive consumer applications where good performance is required.
Its low cost, small size and single +5V power supply make it ideal for automotive CD players, bookshelf CD players, BS tuners, keyboards, MPEG audio, MIDI applications, set-top boxes, CD-ROM drives, CD-Interactive and CD-Karaoke systems.
PCM1712 has the same pinout functions as PCM1710.
