AD1934:  8-Channel DAC with PLL, 192 kHz, 24 Bits

Product 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 sigma-delta (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 ADI continuous time architectures to further minimize EMI. By using 3.3 V supplies, power consumption is minimized, further reducing emissions.
