AD1933YSTZ-RL: 8 DAC with PLL, 192 kHz, 24-Bit Codec LQFP-64封装
The AD1933 is a high performance, single chip that provides eight digital-to-analog converters (DACs) with differential 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 AD1933 operates from 3.3 V digital and analog supplies. The AD1933 is available in a 64-lead (differential output) LQFP. Other members of this family include a single-ended DAC output and I²C® control port version.
The AD1933 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 AD1933 eliminates the need for a separate high frequency master clock and can also be used with a suppressed bit clock. The DACs are designed using the latest Analog Devices continuous time architectures to further minimize EMI. By using 3.3 V supplies, power consumption is minimized, further reducing emissions.
