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 isapparent in both the system and circuit design architectures. By using the on-board PLL to derive the master clock from theLR clock or from an external crystal, the AD1934 eliminates theneed for a separate high frequency master clock and can also beused with a suppressed bit clock. The DACs are designed usingthe latest Analog Devices continuous time architectures to furtherminimize EMI. By using 3.3 V supplies, power consumption isminimized, further reducing emissions.
Applications:
- Automotive audio systems
- Home theater systems
- Set-top boxes
- Digital audio effects processors
At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
