AD1934

www.DataSheet4U.com 8-Channel DAC with PLL, 192 kHz, 24 Bits AD1934 FEATURES PLL generated or direct master clock Low EMI design 108 dB DAC dynamic range and SNR −94 dB THD + N Single 3.3 V supply Tolerance for 5 V logic inputs Supports 24 bits and 8 kHz to 192 kHz sample rates Single-ended DAC output Log volume control with autoramp function SPI® controllable for flexibility Software-controllable clickless mute Software power-down Right-justified, left-justified, I2S and TDM modes Master and slave modes up to 16-channel in/out 48-lead LQFP GENERAL DESCRIPTION The AD1934 is a high performance, single-chip that provides eight digital-to-analog converters (DACs) with single-ended output using the Analog Devices, Inc. patented multibit sigmadelta (Σ-Δ) architecture. An SPI port is included, allowing a microcontroller to adjust volume and many other parameters. The AD1934 operates from 3.3 V digital and analog supplies. The AD1934 is available in a 48-lead (single-ended output) LQFP. Other members of this family include a differential DAC output and I2C® control port version. The AD1934 is designed for low EMI. This consideration is apparent in both the system and circuit design architectures. By using the on-board PLL to derive the master clock from the LR clock or from an external crystal, the AD1934 eliminates the need for a separate high frequency master clock and can also be used with a suppressed bit clock. The digital-to-analog converters are designed using the latest AD...
