The AD1934YSTZ is a 8-channel 24-bit Digital-to-analog Converter (DAC) with single-ended output using the Analog Devices In, patented multi-bit sigma-delta (Σ-Δ) architecture. An SPI port is included, allowing a microcontroller to adjust volume and many other parameters. The AD1934 operates from 3.3V digital and analog supplies. 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 DAC is designed using the latest Analog Devices continuous time architectures to further minimize EMI. By using 3.3V supplies, power consumption is minimized, further reducing emissions.
