数据手册.pdf四个ADC / DAC的八带PLL , 192千赫, 24位编解码器 Four ADCs/Eight DACs with PLL, 192 kHz, 24-Bit Codec
Product Details
The AD1937 is a high performance, single-chip codec that provides four analog-to-digital converters ADCs with differential input and eight digital-to-analog converters DACs with differential output, using the Analog Devices, Inc., patented multibit sigma-delta Σ-Δ architecture. An I2C® port is included, allowing a microcontroller to adjust volume and many other parameters. The AD1937 operates from 3.3 V digital and analog supplies. The AD1937 is available in a 64-lead differential output LQFP.
The AD1937 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 frame clock or from an external crystal, the AD1937 eliminates the need for a separate high frequency master clock and can also be used with a suppressed bit clock. The DACs and ADCs are designed using the latest Analog Devices continuous time architecture to further minimize EMI. By using 3.3 V supplies, power consumption is minimized and further reduces emissions.
