AD1939YSTZ: 4 ADC/8 DAC with PLL, 192 kHz, 24-Bit Codec LQFP-64封装
The AD193X family are high performance, single-chip CODECs that provide 4 ADCs with differential input and 8 DACs with either single-ended or differential output using ADI’s patented multibit sigma-delta architecture. An SPI(R) or I^2C(R) port is included, allowing a microcontroller to adjust volume and many other parameters. The AD193X family operates from 3.3 V digital and analog supplies. The AD193X is available in a 48-lead or 64-lead LQFP package.
The AD193X 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 master clock from L/R clock, the AD193X eliminates the need for a separate high frequency master clock. It can also be used with a suppressed bit clock. The D/A and A/D 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.
The AD1939 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 SPI port is included, allowing a microcontroller to adjust volume and many other parameters. The AD1939 operates from 3.3 V digital and analog supplies. The AD1939 is available in a 64-lead (differential output) LQFP package.
The AD1939 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 AD1939 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 architectures to further minimize EMI. By using 3.3 V supplies, power consumption is minimized, further reducing emissions.
