The AD5668BCPZ-2-RL7 is a dual, 16-bit, monolithic sigma-delta digital-to-analog converter (SD DAC) and features an integrated output amplifier. This high-precision, low-power device provides a throughput rate up to 2 Msps and operates on a single 2.7 V to 5.5 V supply. Its small footprint and power efficiency make it ideal for battery-powered and portable applications.

The AD5668BCPZ-2-RL7 is a versatile device offering a high-resolution, low-power solution for digital signal processing in a variety of applications. It is suitable for audio, instrumentation, motor control, and waveform generation applications. It also has wide operation temperature ranges of -40°C to 125°C.

The device is composed of five sections: input interface, sigma-delta modulator, decimation filter, D/A converter, and output driver. The input interface is designed for 16-bit data transfers. It is voltage compatible and tolerant to a wide range of logic levels. The data input is continuously converted into a sigma-delta bitstream by the modulator. A low-pass filter (LPF) is used to reduce aliasing noise created by the modulator.

The output filter is designed to reduce output noise. It is programmable, low-pass filter that attenuates the sigma-delta noise. The LPF can be programmed to achieve the desired response, such as an IIR filter. The filter can be used to reduce the total harmonic distortion (THD+N) of the system.

The output is generated by a 16-bit, high-speed digital-to-analog converter (DAC) which is fabricated in a switched-capacitor array architecture. The DAC is used to convert the digital bitstream into a continuous voltage waveform. The output driver is used to buffer the output current of the DAC so that it can drive either a low impedance or high impedance load.

The AD5668BCPZ-2-RL7 provides a wide range of features that make it ideal for applications requiring high sampling rates, high resolution, and low power consumption. Its small size and low power requirements make it ideal for portable and embedded applications. With its fast conversion rate, it is suitable for a variety of audio, motor control, and waveform generation applications.
